If I extend your argument to its absurd conclusion, you also get to decide if somebody is “allowed” to love somebody with the same number of chromosomes as themselves, or live in society presenting as somebody with a different number of chromosones. Do you also get to decide if it’s “dodgy” to love somebody of a differing skin pigmentation? Think about what you’re arguing, and you’ll realise you’re arguing a different point to me. We quite rightly legislate against intimate relationships with underage persons to protect vulnerable people, not to tell adults what is morally acceptable. Can you see the difference and understand it?
