It angers me to see these people betraying the ideals of democracy but calling themselves patriots. What they are is hypocrites. As Xanthippas said:
These people are only opposed to fixing America if it's somebody else's idea for fixing America. When it comes to outlawing homosexuality, well that's okay.
Not only is it a hypocritical ideal, it's a bad idea as well. As this blogger puts it:
Still, the absurdity of the slogan becomes apparent if you substitute in slightly more specific localities, as in: "New Jersey -- Love it or Leave it!" or "Rochelle Park -- love it or leave it!" Ridiculous! Bergen County, NJ actually has an "Improvement Authority", for goodness sake. So why should civic duty and good citizenship have such totally opposite virtues from the local to the national scale? It's good to identify and fix problems, but only smaller, local ones?
Besides all that, how can you even fit a realistic political philosophy onto a bumper sticker? I'd be ashamed if my ideas were so devoid of substance you could stickerize them. But then, I find that a lot of conservatives don't have much substance to offer except for wanting everyone to live by their rules.
