In trying to explain (to a fellow atheist even) why I defend to some extent the tone used by another atheist in this article. I explained as follows: "I agree but on the other hand you could say that nothing we say and no matter how we say it will make us seem any more palatable to them. And though it shouldn't matter, I don't think we started the insults, etc. In large part I operate as you say because it's not my personality to be an asshole about people's beliefs (I try anyway) but I honestly feel like that's not a reciprocal action. They fucking hate us and as a result, it's very hard not to hate some of them in return."
But then I also feel this is even more clear: On Facebook I have many, many friends and family of the Christian faith. They do not hesitate or think twice about what their posts in support of their faith (and I'm talking strictly faith here, not politics or moral issues) may mean to those who disagree, whether in some ways it's even insulting to those who don't believe, nor do I frankly think they care. On the other hand, we as atheists have to be very careful what we say and share, to the point where I very rarely share anything at all because to those who believe OUR VERY EXISTENCE is insulting to them.
