I think what he means is that anything sexual at all ( boy, girl, bi, trans, gender fluid, ect) should be just left out of game service where can kids play. It doesn't mean anything is wrong with it at all, of course its a good cause, its just kids have an innocence that they deserve to have. I'd also argue against any toys having a gender label for the same reason.
Lol. If kids can maintain their "innocence" knowing that boys and girls exist, I'm sure they'll be just find knowing there are other genders as well...
