Was the Catholicism question out of line?

[useful idiot]

Abortion is largely still split between religious/non-religious. Those other issues you mentioned aren't. Considering they both belong to a religious organization that condemns the practice strongly (to put it mildly, in a way uncomparable to those other issues), it makes sense to tie the issue to their faith.

If the question had been asked to two people of a widely different religious tradition I think it would have been less acceptable.

I thought they both gave pretty bad answers to the question anyway.
