To specifically make the point that other peoples have contributed to science/tech when you know full well which demographic is overwhelmingly responsible for progress is an act inspired by cultural relativist thinking. If you're only angry at those who have personally harmed you, you may end up being angry with just one school bully but if you recognise the pattern of those who constantly harm your people you can paint blacks and jews with the same brush to keep it simple for rope day. Don't you love your people?
