Well, yes, I have seen certain religious groups whose proportion of "insane" members might be a little higher than in the case of another religious group, let's say... ;-)

But I'm not naming any names.

One could make a case that Democrats and Republicans are insane, because they both keep making the same mistakes over and over again (voting for their party)...yet expecting a different result! ;-)

One could say this of the American government too, in regards to its foreign policy...which is "bomb people into democracy" as far as I can see. (Well, that's what it pretends to be, anyway. It's really "get control of the oil".)
