1. And what gives your preference the right to override other people's preference to be with someone of a different race?
Before you try and say "but I just want to be left alone!": you constantly sperg out whenever someone mentions race-mixing and talk about how it's a moral wrong- the only difference between you and people who rant about "mudsharks" and "coal burners" is that you use polite language, which does count for something but still leaves the impression that you'd bring back miscegenation laws if you could.
2. I realize you like to wave around the "I'm Dutch, ESL, no bully!" flag whenever you say something dumb, but I would think anyone with your clear grasp of the English language would parse Justtocheck's sentence pretty easily. He is not saying "literally every Jew race-mixes"- he is saying "Jews do not practice racial purity internally while demanding everyone else race-mix externally", as your retort attempted to imply.
3. I will literally pay for your plane ticket out of Amsterdam or Rotterdam or wherever the fuck you live and chauffer you myself to a powwow so you can see how "gone in any meaningful sense" Native Americans are. They're better at continuing the practice of their traditional culture and language than you Dutchmen are, and that's with a coordinated effort in the past century to try and destroy said culture that'd make White Genocide conspiracy theorists wet themselves.
