And I don't think anyone is saying it shouldn't be allowed, legally. We're saying, it's bad for society that this has become normal.
E.g. If you lived in a society that found adultery almost
totally acceptible, You could think adultery is wrong, you could not like that society considers it acceptible, but you could still be against making it illegal.
But saying it shouldn't be allowed? Screw that, I like my first amendment.
