Dang, this is yet another example of you making a comment to someone who is responding angrily to a person saying abhorrent things. Your continued defence of polite but disgusting comments pushes out people with different backgrounds, and entrenches fascists who can maintain a polite veneer over their scientific racism or misogyny.

It is unreasonable of you to say that people must remain calm no matter what the provocation is.

Your claim, that there are deep issues to discuss here, is repugnant when we're talking about eugenics.
