This is confusing. 
Surely you said you responded because of the tattoos, the flags and them shouting, "Jews will not replace us!" Your willingness to defend the Jews must be my poor understanding.

I am just as confused by you saying you are, "happy to let them live" - meaning the Jews. It is according to my understanding your choice to let them live as long as they don't threaten you. I always understood the right to life as a basic right. Not something for you to decide based on how threatened you feel.
