because people believeing in stupid things are going to harm themsleves and/or others

What is the abandonment of faith if not enlightenment?

Realistically faith isn't broken by an external influence. When you challenge someone's faith they fall back on the defense mechanisms they've been indoctrinated to use. Faith can only be overcome when the believer comes to his/ her own realization of its absurdity.

As for the reasons why eliminating faith would be desirable, the other posts here provide adequate answers.

It's not to me....and when somebody starts to talk religion to me I get up and leave.

Its a non issue for me. People all have to find their own path, and I sure don't want to interfere with their journey of discovery.

It shouldn't be. To each their own, as long as nobody tries attack or change my beliefs, or lack thereof; I won't do such to them.

The problem is that religions promote the idea that they know "the truth". Hence, even if they are nice people, they are usually going to push their beliefs on others either directly or subtly. If we take acception to that we are considered rude and militant. I don't buy the premise of the question.

Religion is the last bastion of old world ignorance which hurts the entire world.

It really isn't. It's just annoying when believers try to foist nonsense on you or justify their own assininity with vapient recitations of things other people have said in defense of their stupidity.

I do not have to break your faith. I was once a person of faith but have come to see the fallacy in that. People of faith are taught by their religion to make converts. This means they nag me to death constantly in ways of bringing up their god again. Maybe I am just "angry at him" they say. Yes, it is true. I'm as angry at god as I am at the Easter Bunny.
The believer has a different logic than you do. To them their bible is logical. The very idea is a big laugh. They think we take "logic lessons" or courses. It's pretty simple to me actually. They have no problems with the resurrection as a thing that god allowed ONCE. Why can I not believe this also? There is no evidence and it isn't logical. By the time we get to questions like what would I accept as evidence it is so plain they had their minds made up in advance.
A resurrection that god allowed ONCE. Look around you and read other scriptures. The world is full of accounts of ressurection. It's all myth.

That does not sound like something I am interested in doing! My daughter is so deep into her religion and conspiracy theories and it hurts me, deeply! However, I will not try and break her stance on her faith or anything else! I cannot do much now, but be available should she need me...even as my heart breaks!

it isnt but we can hope they do it themselves

Only if the other one is a horse, and you need to ride it for transportation or sports purposes.
