Becoming a colony of the Soviet Union had little to do with deporting a disruptive minority.

and punishing people who were related to Germany only by culture and had lived in Czechoslovakia for generations.

... You mean, by race. And language. And the Sudeten Germans themselves agitated to belong to the Greater German Reich. They got what they asked for.

mm, sudentenland was German lands stolen by the allied powers after WWI.

Eh, those territories have been changing hands for most of recorded history.

ignoring that dont understand what youre saying? are you implying czech needed to import Germans? wouldnt that have resulted in kebabs?

No, the opposite: https://en.wikipedia.org/wiki/Expulsion_of_Germans_from_Czechoslovakia

I mentioned it in reaction to the "it's too late to turn the clock back" bit. It's not, it's possible to get rid of a very large minority group in your country when they're causing problems - it just takes some balls. And a war.

Isnt the Czech Rep succesfully resisting EU attempts to islamify it?

Somewhat, yeah, at least officially, but there's still definitely no shortage of kebabs, blacks and other foreigners, especially in Prague - and I don't mean tourists, although those are an absolute scourge, too. Czech Republic isn't as bad as the UK or Germany, but we still have plenty of people here who absolutely don't belong here. There was even a BLM protest there a few months back - in fucking Prague.
