What I'm talking about is cultural things like slavery, honour killings, child sexual exploitation, blasphemy killings, making homosexual relations illegal. I would hope that we can agree that these are things which are unacceptable or at least unpalatable in the modern world. Therefore cultures where this is acceptable and normal practice are objectively worse than in cultures where it is unacceptable. So when people move from cultures where these things are practised to where they are not, they should either drop them, or move back.
