Mate, british 70 & 80s variety TV were full of cross dressing & raging homos! A lot of people forget that. Loads of sexual innuendo, gay & straight. You are what you are, a few gays on TV ain't gong to change that.
What makes me laugh is this big concern about gays & mixed race people on TV, but no worries with kids seeing all kinds of violence normalised. If your kids see murder on TV, will it make them a murderer?
