parents shouldn’t be able to ruin a child’s life just because they fucked without condom

You have a greater community of people who (theoretically) look out for one another beyond strict family association.

In my experience, the kids who successfully come out and find their way into the broader LGBTQ community are the ones who have family or friends in that community to guide them.

But in practice, your parents make a lot of decisions because you lack the information, the resources, or the social contentions to do them on your own.

Fucking without a condom isn't what gives parents dominion over their kids.
