I understand that, I'm pointing out that your drawing a line separating human vs non human is just as arbitrary as drawing a line separating white vs non white

Yes, its my personal preference. Of course it's might be different for every situation.

Sure there is, but in your view we couldn't say that those people are evil, because in the end it's just preference of where to draw the line, correct? Nazis chose to draw a line excluding jews, and that was their preference

Evil or not is relative. You can say nazis is evil but to the nazis they might not think its evil. To me evil or not is irrelevant. If you dont like Nazi action, then you have to force them to stop regardless.

Ok, so by that same rationale we could say: "Evil or not is irrelevant, but if you don't like animal-exploiters action, you have to force them to stop regardless"

Yes

By that same logic, is it fair to say that Nazis who don't like anti-Nazi action should be forced to stop those trying to stop Nazi actions?

Of course
