Everyone in the comments not actually understanding why it's bad. It creates children that are deformed and don't live long, and as a species we are meant to expand our genes. That's every species. You are genuinely going against everything with incest.
This is disappointing... And I don't mean what happened in the video, I mean using it to justify bigotry "Oh yeah we totally shouldn't teach kids that they can be loved however they are and that they aren't a monster for not fitting into our tiny little conformity boxes" fuck off
Ah yes, because my hundreds of sleepless nights grasping with my own identity, feeling as if I'm some kind of monster and that I can't belong anywhere, not even in my own body, is definitely a fetish. Grow up. Get a life.
