I have little problem with people criticising religious practices in a reasoned debate, but to describe a group of people as 'dangerous idiots' for their religious views, racial group, sexuality, gender seems offensive to me.

There are more offensive things, but I am always aware that if you allow religious groups to be singled out in this way there is the potential for finding ourselves in 1930s Germany. However much I dislike certain religious beliefs or practices I stop short of labeling the followers as a generic group 'dangerous people', sometimes the leaders or foot soldiers but not all the people.

I am willing to admit that I might be a bit over-sensitive on this issue, but there you go, nobody is perfect.
