Why is it just westerners/whites who are expected to cope with a changing population?

Can you imagine a scenario in which say Beijing, or Tokyo, or Jakarta, or Riyadh, or Nairobi, or Lagos, or Mumbai were filled with a foreign population that was greater than 50% of the total population for the city?

Can you imagine a scenario where any country outside the western world had demographic numbers showing that foreigners outnumbering the founding population group of the country in the sub 25 age group?

These scenarios are unimaginable and quite absurd even to ponder for anywhere outside of white countries. And yet, have you been to London? Have you looked at demographic charts?

People can raise objections to the population displacement you seem to favor without it having anything to do with "racism, scapegoating, and a general inability to cope," or "muh jerbs."

There are plenty of westerners who think, "We've got a pretty good thing going here, we've brought a lot of good to ourselves and the world as a whole. And we'd rather not see our civilization drastically altered, because a drastic altering of our civilization will impede our efforts and abilities to go on doing good for ourselves and the world."
