Two words which every internet-using person should know about because they tend to be forgotten: proportionality and sophistication.

Just because there is some element of crime within a specific group within a society, doesn’t mean that the solution is to completely exterminate the whole society.

This is what the word “extremism” means - if you’re an extremist you find extreme measures at least OK because you’ve stopped differentiating and thinking about proportions. And when doing extreme measures to a specific group of people (usually a minority group, or even a whole weaker country), then you’re right-wing extremist.

You wouldn’t want those things to be done to yourself when you’re part of a subgroup that’s under attack. You wouldn’t want to be a victim of extreme measures. That’s one reason why these extreme measures shouldn’t exist in the first place.
