Yes it is unfair. People should realize that the idea of hating all religion for what a small minority do is the same as hating all Muslims for what a few of them do. I would call the person hating Muslims an ignorant bigot, so I guess the same should be applied to those who hate religion for the sins of the minority.
If you don't like religion that's fine, I have no desire to force you to like it, but focus on your own personal reasons and not generalizations about religions and religious people.
I personally am an Atheist because I found that most of the people close to me (outside of my family) who were Christians didn't actually follow it at all and therefore didn't really believe. They were simply going through the motions because that's what they were taught as a kid.
Then I started to think about how the religions of those I knew were decided based on the geography and society in which they are born, and not any kind of logical or theological thought process. So I decided to be Atheist until I have a personal experience that makes me want to be otherwise.
