Well violence is as American as apple pie or assault rifles. But two dudes having sex might turn little Johnny "funny". Because gay people only exist because they learned about it at some point. It certainly isn't some genetic or biological factor, otherwise we're victimizing people over something they can't control or change.Star Trek fairly regularly has one character kill another, often in cold blood, and fully depicted on screen, sometimes with main characters presented as good upstanding people wielding the weapon. As a starting point, the Worf/Duras fight is my first exhibit. The murder of Jadzia is my second. I'm not sure I see why that is 'family friendly' but consenting adults engaged in sex is not?
