Why do Atheists hate Religion?

[IRONDIAMOND]

As an agnostic I don't hate religion. My reasons for not following religion are the aforementioned absence of evidence, rational thought and a general cynical disposition.
I however believe that religion can be of great importance to those who need something to believe in. For those who find comfort in believing that there is support in something.
In my experience I have seen the importance in religion extends beyond a common belief in god. In terms of churches for example, the congregation can form a tight-knit community with meaningful social bonds.
I believe it is important in bringing people together regardless of whether the worship of a god is performed. It does no harm to anyone.

As for the percieved 'hatred'?
Perhaps it is more a societal mistrust of religion. In history religion has been designated as a reason for many conflicts. Even now religion appears in news headlines due to extremist terrorist attacks or instances of sectarian violence. Positive stories of religion rarely appear in the media so its possible to develop a subconcious suspicion towards those who practise religion by wrongly associating them with the minority on the news.
I can only speak for myself here but I do not object to people practising religion. So long as it doesn't harm anyone and as long as they don't attempt to force their beliefs on other people.
Everyone has the right to make their own mind up.
