Hmmmm....thanks. Can I try?
In my opinion only, Grig was calling Christians dirty names because they have defended the true Christ and Christianity; and have (I think) called out Mormonism for the cult that (in my Opinion) it is. Perchance he used the word pig to illicit an image of dirty, muddy beasts in need of a hosing down because he wanted to lash out in, perhaps, just perhaps, some childish anger he may, or may not, have. He didn't choose a kitty, a dog, a lamb, a hamster, a bunny rabbit, a dove, or any other creature as some freeper have suggested - but (maybe, just maybe) he deliberately chose a dirty pig because he wanted to (who knows?) put Christians who have come to the defense of the Gospel of Christ (which needs no "restoration" in my opinion) as dirty pigs. In fact his very words were, Rather than try to wrestle the pig into taking a bath, we are just going to hose it down. This seems to be an indirect way of calling any freeper opposed to Mormons, swine. Just my two cents!
How woooode!
I suspect you are a real joy to live with.
