The author has a point in that the mother brings the child to gay pride in makeup, not that the child goes, as in, by himself. The parents bear responsibility for what their children see and do.
When I read these kinds of stories that are against bringing kids to Pride events they fall into two categories: There's too much sex in the air or the event normalizes (what is for your judgment).
Dressing a child in drag and taking them to Pride is new to me. I see a child getting lots of positive reinforcement at an age when the self isn't fully formed. In an age where parents are more likely to give anti-puberty drugs if their child feels they're transsexual, well, reinforcing gender-bending at a place with all that attention seems like a bad idea.
Thoughts?
