I fully support AT's right to have his opinions about religious people. We all have an opinion of religious people, whether that opinion be good or bad. However, when you have an opinion like the one AT expressed you should not voice it in public if you want people to like you. Sometimes it is just best to keep your true opinion to yourself.
The fact of the matter is that AT's comments would have sparked anger in almost any group they were applied to. Religious people responding negatively to that post does not in any way separate them from anyone else. It does not show that they are easily provoked to violence. If you call anyone weak minded, insane, gullible, etc. they will become angry. Some people will not necessarily rise to the bait, but I am sure that there are religious people on this board who also did not rise to the bait.
For example, I could say, "Believing we are in Iraq to fight terrorism is for the weak minded, the gullable, those who follow, cannot think for themselves, the narrow minded, the fanatical, and the insane." This would target a large percentage of the American public, Including you AT, judging by some of your other posts. I am sure that if there were a large enough group of those people here I would get called a troll and have people mad at me. Does this mean that the above group is prone to violence? Well, maybe that is a bad example
Anyway, calling anyone names is going to lead to anger and violence. Just don't do it unless you want everyone to call you a troll and hate you.
