It's not.
People act like it is, but there's a ton of ignorance out there that doesn't give a fuck about anything. People are ready to riot against SJWs and PC culture online, but in real life if someone says something fucked up in your day to day, no one will give a fuck.
Maybe college campuses are different these days, but personally it wasn't anything like people think it is when I went and that was only like 4 years ago. (Or was it 5, fuck how old am I now)
