Well, I'm an atheist so I'm not very in touch with that.
Here's my deal. I have my opinions. My friends, including those here, have theirs. We agree on some and we disagree with others. That's fine for me. If we all agreed, life would be boring as hell.
That said, I don't feel the need to cast unwarranted aspersions or issue ad hominem attacks on those I disagree with. We disagree. So what? Argue the issues. Try to be constructive. That's my approach.
Perhaps I am comfortable enough with my philosophy that I don't see a threat when someone disagrees with me. Call me old school.
