I am afraid this is actually a true thing, whether you want it to be true or not.
I actually hate this quote because people use it as an excuse to be an asshole now all the time. He’s not wrong in the context he used it, but people twist it. I’ve seen someone explain why it’s offensive to use a term like “retard” to someone on Facebook and then someone else goes “Just because it offends people, it doesn’t mean they’re in the right!”
This. I may not be right, but you’re still an asshole.
