What fun is life if you can't judge other people?

I find it humorous that so many folks on this board attack others who make negative comments about other peoples' clothes, tattoos, vacation choices, lifestyle choices, workout regimens, cars, bikes, neighborhoods, and personal habits. For every person who calls someone/something trashy, there is another responding "why do you care" or "who are you to judge," etc.

Fashion exists so that people with it can make fun of people without it. The class system exists because people at the top of the food chain want to look down on people at the bottom. It's as old as humanity itself. If I want to make a snide comments about douchebags with tattoos, or girls who smoke, or people shopping at Walmart, or your prostitute mother, I can goddam well do so. It's a free country.

You're all millennial assholes who think that personal choices are people's own business. Yes they are, but I can make fun of them if I wish.

ETA: Looking down on people because of their race or sexual preference is not allowed. I'm talking mainly about people's exercise of choices and their bad taste.
