Do Germans that were expelled from the Sudettes have a right to return? https://en.wikipedia.org/wiki/Sudeten_Germans

Does this make the Czech Republic an Apartheid state?

Is Russia an Apartheid state? Can Ukranian refugees return to their homes? What about the millions of other refugees from random places?

There is zero connection between the right of return (which does not exist, refugees have no right to return after they lost a war) and Apartheid.

It's not "Hasbara" (which means explaining in Hebrew, so yes, I'm explaining). It's just common sense.
