You are not alone, its pretty obvious what force of evil overall (even if some local good was done here and there) missionaries have been. And I don't mean just some 16th and 17th centuries horror stories, I mean even recent times.

The idea that christianity is somehow above all other religions, while covering at best around 1/3 of world population... lets say I don't enjoy talking to irrational, highly emotional people on such topics. Where facts become irrelevant so does my presence in discussion.
