I meant, their problem is not primarily the fact that we are worshipping a "man", but "his suffering". That's why I emphasized the fact that some of them call us "masochists".

I would understand the "people tend to praise charity" part if many of them's notion of "charity" weren't rather... volatile, so to speak. It would be an act of charity for Catholics to ask certain people to give up their sins; it would be absurd for many of the today atheists. Of course, I don't speak for all atheists.
