I think most of Christianity's values are terrible: blind obedience, subjugation of women and children, exploitation of the Earth, aggressive proselytizing and eradication of non-believers. The world would be much better off without it. Bertrand Russell's "Why I am Not a Christian" makes the case very well.

Do I think Christianity is bad.

Yes because Christianity is a religion and the foundation of religions are the dishonest "faith" (belief without evidence peddled as facts) (facts are supported by testable evidence) as an honest methodology to find "Truth". This is not only dishonest but it obfuscates the beauty of facts and reason over superstition. The outcome of religion is a mind programmed to accept assertions without evidence reducing the necessary critical thinking skills of skepticism to accurately assess the world.

Christianity is bogus. It does great harm through its practitioners and like its sister religions, Judaism and
Islam subordinates women to men, wages war on the innocent and is destructive to progressive human development.

Belief in a higher being isn’t a problem for me - all people believe in something whether it themselves or the externalizations. Organized religion is where the problem starts. You get this tribalism where a group believes they are right and everyone else is wrong and then try to force their beliefs on everyone else. The teachings of Jesus create a solid foundation on how a person can live a good life - nothing wrong with that. It’s just been perverted and manipulated to meet a particular person’s agenda.

Everyone should be free to their own beliefs as long as they are not harmful to others.

Christianity, and pretty much all religions, is about controlling people. In order for the few to control the many you need some sort of superstition to exert oversite. Then you call all good fortune a reward and and all bad fortune punishment. It is not evil so much as primitive by nature, and this very nature has slowed progress by centuries.

Evil comes into play when you have it justify actions that are immoral while claiming to be the only true measure of morality. Slavery, misogyny, genocide, infanticide, subjugation, and much more are accepted if not encouraged while submission to authority is the underlying principle throughout. To be clear the evil requires human action as a result of interpretation. Otherwise it is no more evil than Greek Mythology or being a hardcore football fan.

Two quotes that help explain:

“With or without religion, good people can behave well and bad people can do evil; but for good people to do evil - that takes religion.”
― Steven Weinberg

“To be fair, much of the Bible is not systematically evil but just plain weird, as you would expect of a chaotically cobbled-together anthology of disjointed documents, composed, revised, translated, distorted and 'improved' by hundreds of anonymous authors, editors and copyists, unknown to us and mostly unknown to each other, spanning nine centuries”
― Richard Dawkins, The God Delusion

All religions are simply how civilizations, throughout history, explained how the universe works, until science and technology came into being for them.

it's delusional of course. sometimes it causes its practitioners to become nasty, even violent.

Why can't we think for ourselves ? Because most of us are cowards who feel better outsourcing our opinions than speaking our own words based on our own reasoning.
'It's not me saying gays deserve to die. GOD COMMANDS IT. WHO ARE YOU TO QUESTION GOD?'
Or something along those brown lines of bullshit.

The most generous thing one can say about Christianity. It gives bad reasons to be good with a whole heap of baggage that ruins lives attached to it. The really pathetic part is the "good" part of the scripture is just common sense.
All Christianity can do is give you a really bad reason to be sensible. Don't murder people. Don't steal. Help the poor. etc. etc.
So banal.

Indoctrination

Man creates. Man destroys. Man created religion. An apocalyspe is predicted in many religions yes? Why strive when the end game designates otherwise?

The Bible was a book written as a means of control. Make no mistake, the people who wrote it also had/have their religion, but the lesser people of this world are not welcome to share it.

As such, Christianity in my opinion is a very bad thing, nothing more than a vector for slavery.

The most damaging things about Christianity in my opinion are:

Firstly the way in which in the evangelical world, it's so much a "me" thing, "my personal relationship with Jesus" and so forth. This causes so much tunnel vision about the plight of others -something the bible itself is not silent about - and makes it the badge of right-wing politicians keen to feather their own nests.

Secondly, making "sins" out of things which don't affect anyone else negatively is wrong. I have no right to tell anyone what other consenting adult they should or shouldn't have whatever kind of sex with. I have no right to tell a woman whether or not she should carry a to term. But Christians, especially political ones, think that they can apply their rules (which they invariably break themselves when it suits them) to everyone else including those who do not share their opinions.

Thirdly, perhaps most importantly, I think the whole concept of vicarious redemption is obnoxious. If you owe me a sum of , you can't pay, but your uncle hands me the that's the end of it as far as I'm concerned. But the same doesn't apply to crimes. If you rape and murder my child, I will not be happy about your uncle taking the punishment, you should, however sorry you were. I would be even less happy if your uncle simultaneously took the punishment for crimes committed against other people which let the perpetrators get away. Yet that in principle is what happens all the time in Christianity.

Oh yes and the whole sin thing and my disgrace is supposed to flow my 0-great grandmother having a chat with a snake - who incidentally was right (about not dying) where was wrong. What kind of justice is that supposed to be?

ANd if I don't believe all that crap I get a free ticket to the -running brimstone barbie.

"Good news"

Christianity has one redeeming feature. Every 25th of December, the Christians are relatively nice to each other!
