Many atheists here who profess a lack of belief in a god or deities do not need knowledge of religions (because their position is not defined as rejecting them so why would they need to know about it?) and will often reply with accusations of logical fallacy, make one line replies, etc.
Maybe. There are certainly people within all the larger groups here who have too much certainty about pretty much everything.
But one of the issues may also be that it's the squeakiest hinges that get the oil...or attention, as it were.
Just on the 'not needing to know about religions' thing...couple of quick points, using myself as an example, since I'm an agnostic atheist, which I guess is what you mean;
1) I was raised in a Christian family.
2) I am a history nut
3) I'm a psychology major (which gives me no great insight, actually, just proof of interest)
If you can tell me any other force that both historically and currently is able to motivate or suppress the actions of millions as effectively as religion, let me know, but there is a clear reason to be interested, and to have knowledge of religions above and beyond personal belief.
For much the same reason, I study politics.
there's a pattern to it and it's really unpleasant if you get on the wrong side of it and many people do it at once. I'm not religious, but I fall foul of it. It not a conspiracy or persecution though, but very difficult to respond to when someone plays judge, jury and executioner at the same time.
Yes, I could see that. I think there are a number of atheists here who steer clear of such threads entirely though. Meh, I have no grand point. I think similar points of view could be put forth about Christians (that they don't have an open mind, that they aren't willing to listen, etc) as atheists, and it would similarly be a vocal subset of the whole lending credence to it. People are people, and atheists (as you know) are no more or less so than anyone else.
