Not long ago, after WWII, all men wore short hair. Anything else was considered abnormal and freakish. Meanwhile, all throughout history you'll find endless portraits with men with long hair, depending on the period. Just as fashions come and go, so do the concepts of what is considered "deviant" or appropriate. These days it's inappropriate for teens to be getting married (or other things) in a much more complex world full of random citizen "strangers" and potential for abuses.

If your marriage is threatened by other people's marriages then you've got bigger problems than they do.

War is criminal yet accepted. Gays are not "normal" (ie. average) but adoring love and consenting lust are hardly criminal. People who wear glasses are imperfect too, yet they are not demonized. Everyone is "different" in numerous ways. It depends what the tolerances are of the times. Presently the Trans Agenda further erodes the family unit and communities with their weaponized social engineering shit. Consider who controls the banking, the media, and the government - Zionists. They lies and lies all the problems.
