Either you are being sarcastic, or you've never made a profile there xD
People get told to die each day on Tumblr if they have a unpopular opinion, like you shouldn't bash men, there's such a thing as reverse racism, or you believe that men who wear Fedora Hats shouldn't be bashed/ online bullied....
If that is one of your opinions, you either get tons of followers or keep your trap shut, because you'll be flamed till you don't feel welcomed there anymore, many people have been forced to close their profiles there, just for speaking differently.
A young girl was recently forced to close down her profile just for saying that Disney's Frozen wasn't racist.
Tumblr is the hell of the Internet, they act all social- justice, but are not scared to tease, bully or flame with somebody they disagree with, it was a fantastic place back in 2010- 2011, but since late 2012 it's gone to hell.
