You could be married and raise someone else's kid just because your wife got divorced from a former husband before marrying you. Or you just happen to have married a widow with a child.
Correct me if I'm wrong but Trump had kids fom 3 different wives. And Melania raised at least one of them since Tiffany was only eleven when Donalds married Melania. And he's ben involved in adultery many time, even with pornstars. So yeah, bring back Adultery laws and may Trump be the first to be trialed for adultery
If you want adultery laws, I suggest you move to Saudi Arabia, Qatar or maybe the UAE, countries where women get stoned for adultery ou pre-marriage sex.
And there's something else you're gonna love about these countries : they don't bother with gay-wedding cakes or whatever: They execute gays (or put them behind bars for the rest of their lives).
