I assume it doesn't say because there are games with LGBTQ+ content that is sexual and ones where it is not.

If you google Tankard-Reist you'll find it's not a conspiracy theory - she has actively tried to block queer representation at every level in every way for decades

It's not all that much of a conspiracy theory as those pushing this line at the payment processoers openly advocate that since LGBTQ+ references sex by way of sexuality and gender, then that is sexual content, and is therefore inappropriate for children. This, of course, completely ignores heterosexuality and cisgender because they consider queer people existing to be harmful to children. And trying to get through to them about how important age-appropriate sexual education is in combating child abuse is an exercise in frustration.

politicians have literally said that the reason for censorship bills about the internet are specifically to go after lgbtq spaces.

How can you know a game is LGBTQ+ if they don't talk about sex/gender? They look like normal humans to me, which differ in sexual preferences only? Example: How can you say this guy is gay without knowing his sexual preferences?
