what makes incest immoral\wrong?
a gay man here , and i've been down a rabbit hole lately watching debates about the morality of homosexuality and i noticed that conservative people who tend to be against homosexuality always bring up the incest argument to declare that love is not an excuse for having legitimacy of intimate relationships , ive been thinking about it A LOT , ofc i'm not talking about the case where incest results in children that's obviously wrong , but if two grown people of the same family decided to get intimate with each other and have a sexual relationship (with no kids or offsrping) how can this be immoral and how is it different from queer relationships?
