Why is it wrong? On what grounds? By which principles? Why is that objectively wrong, and homosexuality is not objectively wrong? They must be something to measure action by. But by stating that no one gets to decide, then there can not be objectivity.

For much of human history torturing a child would not be seen as morally wrong. Especially under the idea that they held, which was that the strong can take from the weak, or exploit the weak. What is stopping someone from saying that we should return to that era? We can’t make a value judgement if we say that we can’t decide right and wrong.

Moral relativity, and “no one gets to decide”, undermines even something as obvious as this.
