Well, what is your standard for holocaust?
Also, your disingenuity (implying without stating that 5% is small) already convinced me that you're not in good faith, so this wouldn't be productive anyway.
But if we want to continue this thread it appears that most wars in urban areas have a ratio of 30-90% civilian casualties https://en.m.wikipedia.org/wiki/Civilian_casualty_ratio
Yeah, it's more complicated than that, I'm glad you agree.
Can you also say jews in germany were at war during WW2?
