All religions and cultures are capable of turning fanatical enough to be called "fascist" if its members feel threatened enough. Germans felt that threatened in the 1930's. Moslems apparently feel that threatened today. But most cultures and religions, "organized" or not, do not, I believe, feel that threatened at the moment.
A, It is the ones that aren't "threatened", that engage in the "You must be of my faith or you surely will go to hell.", and then "help" folks on their way that bother me the most. But now, speaking of "threatened" bringing about fascist tactics, our government {culture?} seems to fit the bill right now. Peace and love, George.
