Atheists can hate religion without hating the religious. In fact, in most cases, we pity those who are still confined within their mental shackles and having to live through the abusive relationship that defines theist belief systems. That is why we hate religion because we see what it does to people, it poisons them and warps their thinking. It is a virus of delusion that instinctively attempts to reject the antidote of reasoning and critical thinking because part of its symptomatic profile is to convince the sufferer that they couldn't possibly live without it.
