Why a weird, distorted take. People who put “LGBTQ Ally” in their signatures aren’t being phony. They have friends or family who are LGBTQ, and being visible is one way to support them. If it’s unprofessional to be an ally to LGBTQ friends and family then it is easy for hateful folks to claim it’s unprofessional to even be LGBTQ. Why does it offend you so much for someone to say “I support my gay friends”?
