Our country decided drinking was illegal too, for a while there. And what did that result in? Organized crime; the mafia. Our country makes mistakes in its legislature, and sometimes they take a long time to fix them.
But as poopoo said, my point was that those who use religion as their backing
are on thin ice, as it hasn't always been that way.
Also, as for slavery: slaves were fully grown men, women, and born, fully developed as human children. No one owned embryonic slaves, lol. Remember, to me a young zef is not a fully developed human and thus doesn't have the same rights as even a 20 week old fetus.
