You don't have a problem with children in drag (where the 'drag mother' is a sex offender), or children being taken to venues to watch sexual performances and interact with the performers?
The second has a fully-clothed lady in makeup and headdress doing a dance that involves flashes of her underskirt, and is far less sexed up than, say, a can-can dancer, of which I personally saw plenty growing up watching old cartoons and TV shows (and have since ended up posting on the Hacker News forum which I guess is not necessarily the best endorsement).

As for the third link, I've personally found Andy Ngo to be a completely unreliable source. That said, I do believe sex offenders should not be around children, but maybe let's start with places where they're a bit thicker on the ground.
