When people get all weird about distinguishing "ethics" and "morals," and when they're afraid to just call things good or bad. In Catholic high school one of my teachers said the difference was that atheists can only be ethical and not moral and that seemed like a load of bull so I just use them interchangeably. But now people seen to make the distinction in the other direction, what with the whole, "Up yours, woke moralists!" bit
Anyone who fucks around with these word games is hiding something, possibly even from themselves. Ethical, moral, good, beneficial, productive, pro-social, I don't care what term you wanna use, if it's good it's good and if it's bad it's bad. When someone says their views are ethical but not moral or moral but not ethical, get ready to hear some fucked up shit.
Maybe there's some academic distinction where it's meaningful and ok but I'm just going off personal experience.
