Back to the topic, I don't see how an objectionable touching becomes any less objectionable because it is conducted by a person of the same gender as the victim. As far as I'm concerned, genital touching by people with badges is wrong and un-American whether the perp is a person of the same gender or of the opposite gender.
We have at least one transgendered individual here on FT who is open about it - which gender is allowed to touch them?
