You're not confused, and you felt the irony in my post. I wrote it's trying to be PC, and I didn't touch base upon what PC actually means - it's a broad term, different in everyone's eyes. Yes, Tumblr is bowing down to someone's standards, I called that PC, you are bothered by that statement - let's agree we disagree but you got the big picture and that's what matters.
That's fair, tumblr is very much being politically correct in that sense. I'm just so used to it being a right-wing insult against basically anything leftist.
