I'm with Alcon on this - I think you're imagining a lot of this perceived hatred of religion. Yeah, there are some who do but I don't think most of the secular folks here go so far as to hate it.
I think this is flat out wrong, to be frank. I do believe some Agnostics/Atheists hold the belief that they're unfairly chastised and singled out by Religions. That's true to an extent. However, the same is true for Christians. This isn't a one-sided issue, folks.
I'm talking about agnostics/atheists actively hating on religion on this forum, not necessarily in general. Certainly many of us feel rather chastised by some religious folk, but most of us, at least on this forum, don't hate religion. Yeah, we criticize it when a discussion on the matter has been opened, but that's natural when you hold a different set of values and beliefs. It's not the same thing as hating it though.
