If you see someone whose dark olive skin tone and clothing suggests that they are from the middle east and you think:
“I wish those damn towel-heads would get the fuck outta my country!”
You are a racist.
If you see someone stop what they are doing (either because of the time of day or a meal is about to start) and start talking to invisible beings, and you think:
“Damn, I wish people would use common sense and reason rather than believe in the superstitious ramblings of bronze-age goat-herders.”
You are an Anti-theist.
