I've had to do that. Just do it, and if they're offended that's their own problem. You aren't obligated to follow someone if they post crap you're not interested in. I got unfollowed by plenty of people for posting anti-fem stuff, and my feelings aren't hurt.
//follows your tumblr because awesome.
I think the one in my sig is my alternate, themed one. My main is the same username as on here. I'll follow back too ^_^
Followed.
(******** i am adding people to my block list tonight)
Thanks!
And yeah I've been thinking about doing that too. Some people I follow post otherwise good stuff so for now I've kept them despite our different stances on feminism. >A>
