I have absolutely no interest in protecting my ethnicity. Plenty of ethnicities have gone extinct and I fully expect most extant ethnicities (and religions) to fade away eventually too. No one will be upset when there are no more Jews any more than they miss Manichaens or Hittites. Borders and superstitions serve no practical purpose. To be clear, I'm not advocating genocide or violence of any kind. I'm just saying attrition is inevitable.
