Why should we be having social discussions about whether or not genocide against a particular out-group is acceptable? Would the proposition that slaughtering an out-group be a good faith discourse about the best path forward for society? If not, why should we have that discussion at the cost of other discussions?
Those are real problems, yes. But it should still be allowed to question the solutions people claim to have to those problems. The author here claims that you shouldn't be allowed to question solutions, if you do then you are evil and should get rejected by society.
