Wetware problem thinks that Transmen are privileged shitlords who can't be feminists: http://wetwareproblem.tumblr.com/post/139802475981/you-said-that-transmen-cannot-be-feminist-because (archived version here: http://archive.md/4XXiR )
Isn't feminism about equal rights for all minorities, regardless of their gender/sex, and not just women? Even if trans men are men, they ARE a minority.
It seems like a lot of Tumblr feminists enjoy disregarding the fact trans men were raised as women and not raised in the same way a cis man would be.
