Do you find that sometimes atheists get very aggressive and disrespectful in their arguments?

I have started to notice more and more than some atheists tend to get really insulting and stuck up while discussing religion with someone with a religious faith. I don’t even know what word to use but it’s like they get into this superiority complex and go below the belt kind of.

It particularly pissed me off today at work (although I was trying to have a good day) when a co-worker was talking to this other co-worker (a lady). This lady is very religious and my other co-worker was telling her how he thinks religious people are automatically bad people. I was shocked. I have my reservations about religion but I wouldn’t make a claim like that. That’s not all, he raised his voice and started saying nasty things like attacking her faith. I felt really sorry for the poor woman because she didn’t even know how to react to this. But like I said this is not the only place that I’ve noticed.

And yes I know religious people get cocky too so don’t give me that answer.

How about you guys have you noticed this or experienced this recently?
