I felt moved to respond:
...We do have freedom of speech in this country. So, to an extent I suppose, we have the right to be rude to others, irrespective of their stations.
But I wonder how politic it is.
Incidentally, while I personally regard the practice of homosexuality as a sin, I favor moves toward securing full civil rights for gays and lesbians, including an openness to the establishment of some sort of civil recognition of marriage-like relationships. (This I deem no threat to marriage or the Church. I regard "marriage" under state laws to be a different, though often coterminous, institution from the relationship we recognize within the Church.)
I say all this by way of explaining that my rejection of rudeness has nothing to do with a bias.
