When does anime promote degenerate incest so much? A girl like this would be burned at the stake for openly flirting with her brother! BURNED.
They're not, she thinks they are, he knows the true. So in her mind she wants full on incest. In his mind he just doesn't want to fuck his adopted sister because he's trusted to take care of her.
Relax, op, it's all part of a secret plan to destroy Japan. Kids grow up watching incest shows, reading incest LNs, grownups are more and more tolerant to it, today's kids grow up and marry their siblings. Couple of generations and it's mongoloids everywhere and even one generation should be enough to fuck things up on the level of the nation as a whole.
Must be the chinese, the bastards.
>tfw no clingy cute imouto to embarrass you in public because she loves you so much
It's those small things in life really
Why prohibit incest with the excuse of it shitting up the gene pool and creating retards when OP idiocy proves that incest or not, retards are being born left and right?
Might as well go full britbong and start mixing up 2D with 3d, at least that way some sensible human can say with certainty that those guys are retarded and not just pretending to be.
Why do you believe island = inbred?
Most people lived in small villages until a few hundred years ago - whether located on an island or the mainland made little difference, as the migratory distance of people was less than the size of these islands on the mainland.
>go on vacation to "freshen" up the gene pool
Where do you get the idea that this was a thing from?
A population of a few thousand is more than enough to prevent effects of inbreeding indefinitely.
Creating new hybrids only has a notable positive effect when the population is breeding with siblings for generations levels of inbred and the rare negative recessive traits have had chance to become common.
>the rest of the intelligent planet.
The average person has no clue how genetics, nor inbreeding works.
They seem to think there's some kind of "retard baby" activation mechanism involved.
>imouto is based
>look at yours sister
>nigga do my homework cause im braindead and I won't even bring you any shit you asked me to bring
>cry in corner
>People who fantasize about incest with their mother don't have one themselves.
I wuld fug imouto if there wasn't a risk of it backfiring horribly.
Can't imagine how awkward life would become after being rejected for such a thing.
