The Prussians and Prussianism were the project of a dynasty of megalomaniacal assholes, and the 2nd and 3rd reichs damaged Slavs/Eastern Europe massively.
And the various Teutons and other western Germanic/Frankish/Latin tribes enslaved and molested the Slavs for the better part of a millennia.
And the current Germans have gone right back into lemming mode due to the previous Germans big fuckup and they are trying to force everyone onto political correctness and other leftoid globalist shit through the EU, of course in ways that massively benefits them.
Slave literally comes from the word Slav.
So, yeah, we kinda have historic reasons to dislike and suspect them, sue us, kurwa.
An old German saying is
Please think of all the things we've done for the world instead of the things we did to it.
