>>That's what your religion teaches

More precisely, it's how Rick interprets what he has read and heard.
It's almost impossible to find a "pure" version of a faith as expressed by an individual because no matter how disciplined, an individual will inevitably color the interpretation.

Catholics, for example, have seen a dizzying array of "teachings" over the past 40 odd years from a string of popes whose interpretations have been all over the lot. The contrast between the teaching of the last two is especially striking.

If you find proselytizing to be offensive, stay away from people like Rick.
They let us know what they're about pretty quickly and after that if we hang around and engage them, we're inviting it.
