It is homophobic to post homosexual images that may jeopardize a gay persons employment. Even if the activity filmed violates known company policies. We all have an obligation to review, adapt, and modify our heterosexual standards of behavior when viewed through a LGBQT perception.
It's homophobic to fire someone just for having gay sex at the workplace. What could be more gay than having gay sex, and they fire him for it? Classic case of homophobia. Gotta go file a lawsuit, stat!
