I'm of more or less the same belief. Women are a lot to handle, but I honestly don't really feel one way or another about polygamy. It's not outright forbidden in the Word but I'd wager that most men who think they'd be able to swing it, can't. If you're going to have multiple wives you better be damn sure you can provide for them, and love them. I think many men think they can handle it because they watch their harem isekais or other media and think it's always sunshine and rainbows. It wouldn't be, that's not real life. But if you can handle it and be a good provider, I honestly do not care/don't see a problem.
