So.. don't use Vore?
It's really not black and white, it's a spectrum. People have a right to have their sexualities safely, and other people have a right to not be exposed to sex they don't want. The extremes on both sides are unfavorable. On one one side, total suppression of all sexualities in any public place; should you be able to make two men in love not hold hands in public, because it bothers you to be aware of their sexuality? On the other, total sexual freedom, and being forcibly exposed constantly to every expression of anybody's libido.
It's not easy, because the actual middle ground does involve compromise on both sides. Some people don't want to have to be aware of sexualities that aren't their own at all, and it's unreasonable. Some people don't want to be made to hide their unusual kinks in public places and feel that it's wrong for them to not be able to sexually signal wherever they want, which is also unreasonable.
Either way, it still is about consent, and the consent of bystanders counts too.
What is shameful about vore? You really don’t have a good answer do you? Does the mere existence of vore just make you feel yucky? Is that all?
It doesn’t matter. Vore is harmless, by definition, it is a purely fantastical kink, totally harmless and without ethical considerations because it cannot physically be acted upon in real life.
Kink-shaming vore is about as ridiculous as kink-shaming tf porn. it’s not real, it can’t hurt you. “I don’t care what people do in their own homes” dissemble all you like, but if you didn’t care you wouldn’t be whining about it online.
If there’s anyone who should be ashamed here it’s you.
For now, I don’t care about what people do themselves or in their own home and such, but don’t rub it in other people’s face. If you’re saying that it should be public and it’s all good, we’re on very different levels and there is no actual middle grounds here.
