Gonna step in here only because in seeing two things that just aren't sitting to we'll with me here.
First is the idea that people are somehow "closed" to rational debate when slavery is involved. This is simply untrue. The debate of slavery ended arguably before the American Civil war did. Calling it bad and walking away there, is closer to an act of simple time saving than it is being rationally closed minded. (Cold Blooded murder is bad, refusing to debate it's potential merits is not close mindedness, for example.)
I would ageree with you there. In my opinion people that refuse to debate whether slavery can be justified and if so, in which forms, are
not entirely closed to rational arguments, they usually simply safe time by choosing not to in certain, specific circumstances (with which I want to say: the don't debate it in everyday circumstances).
That is exactly why I think that from people acting like that
it doesn't follow that there is no questioning possible of whether slavery is in fact bad. Mizhara seems to be pretty comitted to the view that one can't possibly question whether slavery is bad or not, that it is a 'simple matter of fact' that it is wrong and that you don't skip rational arguments about it because of time constraints, but rather because they are not needed.
I on the other hand would say that you don't need to debate all the time whether slavery is bad or not, exactly because there are rational/reasonable arguments against slavery.
The second issue I have is the incredibly slippery slope of comparing "calling Amarrian's bad," with the ghettoization and eventual mass elimination of Jewish people (Aka 'The Holocaust'.) Granted you didn't exactly name, names here but I think we'd all be kidding ourselves if we thought you were talking about something else.
That's not what I meant, there: What I meant is, if you don't allow for rational argument to be the thing that decides what to view as acceptable and what not, but say that if something is without rational argument viewed as acceptable or not and say that rational argument is unnecessary, then you have a strategy of justifing things as acceptable that immunizes it from rational critique and which then can be used to justify even things that are obviously evil to us -and arguably, by all reasonable standard should be.
It's not about comparing "Amarr are bad" to anything, it is about how any way of determining what is morally/ethically acceptable or unacceptable that is immune to being rationally questioned is a potential strategy to justify horrendous acts and immunize them from rational critique: And that therefore that we shouldn't employ such strategies at all.
Generally speaking though I' do have to agree with Stannis of this one (he being the true king and all.) Individual acts either good or bad should be judged individually. Tallying everything up is not only philosophically dangerous, but also nearly impossible.
That is the core of my point, trying to bring this to bear against the position of Mizhara, which seems to be one that allows for tallying up bad against good - unless it is about slavery, in which case the one practicing it is evil for all intents and purposes.
In short.
Slavery = Bad
Amarrian's = People (capable of both good and bad but cannot completely represent inherently one or the other.)
Exactly what I was trying to argue for!
