By that logic, how can we even justify finding Nazi ideology disgusting? "Sure, a lot of Nazis committed a ton of heinous crimes, and their value system told them it was good and proper to do so, but some of them are probably nice people who didn't commit murder!"

To be clear my point is that not all cultures are equally good - due to their different value systems. Pretending they are always leads to the most harmful, unfair, and cruel ones taking advantage of the most trusting ones.

Again, nobody here is arguing for harming anyone, nor for taking any action at all towards those of that ancestry that aren't doing the crimes. But I'd be all for deporting those that do.

If some individuals are committing crimes, why isn't the normal criminal justice system the answer, instead of deportation?

And deport them to where exactly, and on what justification? They've been in Europe for a thousand years and are effectively stateless.
