People who self identify as Christians these days violate a huge number of rules that didn’t used to be violated frequently when Christianity was dominant.

So yes, it could be the case that the flavor of selfishness we are discussing is on the border and would be debatable. But if the sort of people you are referring to are the same sort of people I’m thinking of, I don’t think most Christians from say 1850 would accept them as Christians. The social bar for calling oneself Christian in current year is practically nonexistent. This is different from no true Scotsman.
