Prop 8 supporters just shut the F up!

It's sickening enough that so many people voted in favor of Proposition 8, but it's even worse that they then have to brag about it! Two of my friends in California posted their sorrow on Facebook about Prop 8 passing and in response people on their friends list proceeded to explain how they actually love gays, but had to vote to "preserve the sanctity of marriage" or to "just do what I think is right." What is the point of this? I am not asking a rhetorical question. What do these Prop 8 supporters get out of telling a person directly that they voted against their equal rights? If you're an ignorant ass or a religious nut job can't you just keep it to yourself?
