Twitter may not be quite the downfall of humanity, but it's doing a good job of exposing the hidden bigotry of its most popular users. Roseanne Barr (who is running for president), angered the trans community after one of her followers tweeted that Green Party candidate, Jill Stein, "“is also in favour of letting men into spaces where little girls get changed." [the women's bathroom] Barr replied, "if she has a penis she is not allowed in." The full exchange can be viewed here.
Sigh. Cis people (and I am among you), just stop this right now. The bathroom argument also hearkens back to an outdated version of feminism that excludes trans women on the principle that they were not "real" women, therefore didn't have a place in the movement. And unfortunately, that attitude still hasn't entirely died out.
