How "logical" is it to say that because I have some values, they are indistinguishable from justifying slavery?
This sort of "there is no truth or good or bad" is exactly the sort of reasoning that's used to brainwash people into supporting anything and everything. Because once there's nothing true, there's nothing false.
If somebody is feeding you this line of reasoning, or some group, or some forum, I would recommend trying to reconnect with mainstream human thought and value of human life for a bit, and see if the nihilism still seems logical. Try to read a mainstream history of the Nuremberg trials, for example. Or read a book about the Reconstruction and the oppression that happened even after slavery was abolished.
It never ceases to surprise me that people wave around the Paradox of Tolerance as if were an immutable law of physics rather than merely one philosopher's opinion among many.
It seems that if you can't deal with what was stated and have to fabricate positions in order to argue against, that you are not posting in good faith.

This is a complete misrepresentation of what was written, as if you were talking about somebody else's comment. It is bad faith to misrepresent the position of others, not a cliche.
The clearest guideline that I have seen is the Paradox of Tolerance, where we must stop some speech in order to make room for as many as possible. Fascists hate this, because fascists are the ones who demand total and perfect freedom to act and speak as the wish, up to the point of being allowed to perform violence on those whose speech they don't like. Which is why the fascists were chanting "Hang Pence" as they stormed the capitol.
Don't you dare try to accuse me of being arrogant for judging fascists, and don't you dare accuse me of trying to be the ultimate arbiter of good and evil. I can name fascists as unacceptable to society without being an ultimate arbiter.
We are in dangerous waters in the US, and all our words mean something right now. Will we fall for the lies of the fascists who say "let us violate all social norms with our speech, and we promise we woke take over with violence than force you to follow our norms with violence," or will we stand up to them and enable as open a society as we can?
