Part of the Common Law (otherwise know as the English Common Law), states that marriage is between one man and one woman.
Along with habeaus corpus, trial by jury, etc are all components of English Common Law.
That’s correct. So I don’t think the gov’t has any business telling the majority of people that they have to reject what has been common to them for centuries, especially since it is against many’s religious beliefs. That leads to forcing schools to teach kids about things that shouls be left to the parents to teach.
