Am I the only one genuinely shocked about Muslims supporting slavery?

It been months since I’ve learned that and I’m still shocked. Why isn’t this more talked about. Why is saying that acceptable and not banable?

They say that you can’t enslave any freeman. But here’s the “loophole”, when you capture enemies in a war and make them a captive then it’s free game. What. That’s exactly slavery.

Then they say that they can’t end slavery cause their economies depend on it and also the slaves would be left without house and a job. Why should we care about your slave economy? How else would you free the slaves, what do you propose? They propose that Islam encourages freeing slaves and by a period of time enough slaves would be freed to completely end it. They’ve been using this excuse for 1400 years and guess what. The population of slaves has not gone down.

Please tell me I’m not insane. What is going on. They give themselves a pat on the back for being anti slavery when that’s exactly the opposite. It’s sickening how disingenuous they are.
