"Fight fire with fire" is perhaps the most asinine thing ever said.

The literal perspective is ridiculous. You fight fire with water and by eliminating the oxygen (which is, in the firefighter's parlance "letting fire eat itself"). Imagine trying to put out a fire with a flamethrower and some gasoline and you see how dipshit the idea is.

I've heard people I love and respect say things like, "Colin Kaepernick has nothing to complain about. He's a freakin' millionaire!" at which point I'm thinking, "Wait a minute, he's not protesting for himself. It's for racial injustice. What you're saying makes you sound racist. I don't want to think of you as a racist. I don't want to think of you like I think of our president and vice president."
