This clearly isn't going anywhere. Let's pull up https://de.m.wikipedia.org/wiki/Liste_von_Terroranschl%C3%A4... instead. It seems roughly 50/50 islamist and Nazi terrorists (with 2 left terrorists mixed in.)

If we can agree that half the problem is Nazis and the other half is Islamists, I'm OK with that. Deal?

(Yes I'm ignoring the left attacks. They targeted objects/property, not people.)
