I'm white, straight, and republican. How else can I piss you off today?
I'm including a link to a similar sticker below. All I could think was "really dude? Are you really a jackass, or do you just play one on the road?" No one is pissed off that you are white, straight, or even Republican. They are pissed off that your sticker makes you sound like a racist homophobic ASSHOLE. You just go ahead and assume otherwise. No changing stupid.
*I'm a stupid moron sticker*
