honestly all of you can go fuck yourselves, this is why i normally don't engage. literally nobody here has presented an argument about why incest is supposedly morally wrong, everyone just keeps calling it gross and disgusting and asserting that as fact. with the sole exception of the one person who equated incest to CSA
Since the offspring coming from incest could possibly end up with genetic problems I don't really agree with it irl, but in fiction I don't really care, people can write whatever the hell they want.
