Honestly, I don't think we have a lot to worry about from parents stopping their kids from playing games because of this stuff. We live in a time when the average age of gamers is over 30, and a sizeable chunk of the people popping out kids these days are gamers, or were at some point. The days where parents are going to attack all games because of the content of a few is, if not gone, at the very least quickly diminishing. There is no existential threat to gaming here.
