Marriage is something that has kept stable societies for centuries. The problem is the concept of marriage has been corrupted by feminism and government getting in the way. Marriage and government has been captured by both leftists and tradcons - even tradcons cuck by blindly pushing marriage without realizing our divorce rate is high, and we all know why leftists have ruined marriage. No-fault divorces (that one is on Ronald Reagan though), promotion of hedonism and hypersexualization, hyper-individualism stemmed from first and second wave feminism, excessive amounts of activism by these feminist groups to undermine the institution of marriage...

If you can find a way to completely annihilate feminism from government it'll go a long way, but you're going to have to wake the tradcons up as well.
