There's no point in asking things like this. If you somehow, magically, got 99% of all RP supporters to do things you ask, you'll have the 1% who won't and the media WILL focus on them and everyone else WILL equate their actions to the rest of us. I'm certain most supporters are courteous, but everyone focuses on those they dislike anyway to paint a bad picture of us. If people can really be persuaded by our side and what's holding them back are our supporters, it's clear they're only in it for their own vanity and we'll never change their minds anyway unless we're some sort of exclusive club they can brag to their friends about belonging to.
I'm certain there's a ton of Palin supporters who are a bunch of assholish douchebags. I KNOW there are a ton of Romney supporters who are, but no-one ever talks about them. No-one else is expected to police their supporters, because the idea of it is ridiculous. Why are we the only ones? It's a little strange, isn't it?
