I think honestly many of those folks haven't really thought about it, but are just parroting something they heard from their clergy or something. I've had conversations with some devout people who were surprised to find I'm atheist. I like to think they change their thinking after realizing I'm nice, ethical and moral, without a belief in god/s. I do feel that as more of us nice atheists come out and create awareness, that myth about atheists being evil will evaporate.
Not offended, no. However, it does bother me that, Christians especially (or maybe I think primarily of them since they are so influential and there are so many of them in the US), feel they own the moral high ground. I believe there is a small fraction of Christians who truly believe and who honestly try to live a "godly" life, following the commandments, etc. That said, I believe the majority of them are complete hypocrites. The spew their "morality" and then break all their own rules. The reality is that everyone has morals. Everyone has their own moral standard. There are bad people in the world with "bad" morals, who don't respect the general, common-sense behaviors of society, many of which are enshrined in law (murder, theft, assault are all illegal except in self-defense). Christians and Atheists exist across the spectrum of morality (good & bad). I feel that the percentage of actual "good" Atheists might be higher because Atheists at least give thought to what they are doing. Many religious people are kept in check by their fear of divine punishment. Morality is a subjective thing and the religious do not have a monopoly on "good morals."
Not really, but I'm a behaviorist. I try to fully own my own emotions, thoughts and reactions, therefore I understand what others think and do is on them and out of my control.
A few theists are toxic, but sometimes it's funny instead of offensive. There was fellow supervisor (thank goddess he barely impacted my work) and there had been a little tension, but nothing big. He found out I'd performed some gay weddings and angrily asked me, "you're just an unrepentatn sinner".
I said, yeah man. Strangely that worked for him, he just needed to put me in a box and that decreased our tension.
I still smile when thinking about that exchange.
I do object to the "holier than thou" attitude some theists hold over non-believers because it is so obviously unfounded. Morality finds many of its tenets in the foundations of the biological blueprints for survival of whichever species. Just because someone wrote it in a book doesn't make it their property alone. Indeed so many immoral acts have been committed down the centuries in the name of theism that they should perhaps apologise instead of berate?
Let's see now, I get my morality from life experiences, family, friends, innate sense of empathy and compassion for others, books, schools, the golden rule of society, etc. When I'm faced with a decision to do right or wrong, I immediately know it and it has nothing to do with scoring points for Big Daddy in the sky.
It's hugely offensive. I'm a very moral person. In fact some of the theists I've encountered during my lifetime have displayed a shocking lack of common, basic morality.
Many are hypocrites, yet they look down on us, patronise us and claim the moral high ground. To dismiss an atheist's morality is to invalidate the whole person.
No, they exist inside the bubble of their traditional paradigm. Unless a person expends the personal effort to expand and try to burst that bubble you cannot really expect them even to see out of it.
That is part of why it is important to speak up, it is like sticking your head into that bubble and letting them know the world is bigger than they currently think.
I don't think they realize how arrogant and impertinent such a contention is, so I don't take it personally. However, it IS tiresome because it's so drilled into them, and the flip side is that they really believe that they would become depraved without their imagined godly morality. That's, after all, why they think atheists would be depraved, licentious, etc. At least there's a certain internal consistency to that notion.
It usually takes them by surprise if you force them to apply the notion to themselves by saying that it's too bad that they think themselves so evil that they believe themselves barely restrained from pillaging and raping but for their god holding them back from what they really want to do.
