This question was closed, and even though I have edited it, it still doesn't seem to be eligible for opening. Why?
I still consider the question subjective and argumentative, you're asking about a topic where people have strong opinions, you quote an extremely inflammatory opinion about that topic, and "slaves" is also not exactly a neutral term. Even restated in neutral terms, I would consider it "not a real question", your terms are not well defined, it is not clear what you are really asking about.
If you can convince 5 people with >500 repuation to open it, fine. I won't use my supervote as moderator to reopen that question.
Unfortunately, this is not the right place for questions of this nature. That does not mean that it isn't a good question, but just that it isn't the type of question that we can help with here. There really isn't a a claim made here that can be verified, so it is off-topic. Also, the nature of the question is subjective. Ask 100 people, and you are likely to get 101 answers. It is too opinion based. Most political and legal questions are like this.
Please do not take this as an insult, as it is not intended that way. We just have to stay within our narrow scope of support or die by scope creep.
As of my writing this, there are no re-open votes.
A good question for here has a claim that can be objectively tested. It doesn't ask for a list of pros or cons. It asks one question that is amenable to an objective answer.
This question asked for pros and cons, and concluded with an inflammatory question that looks more rhetorical than actual to me.
