Digital rights activist Evan Greer confronted Mace, the South Carolina Republican who has filed a bill to bar transgender people from using single-sex bathrooms that correspond to their gender identity.

A prominent digital rights activist, who is transgender, confronted Rep. Nancy Mace at a public event Thursday.

Rep. Nancy Mace fired back at a transgender activist who was thrown out of a tech conference for protesting her bathroom bill — later calling the agitator a “raging lunatic, pretending to be female.”
