Also, someone fact check if im wrong, bit i am sure the Antifa flag is very similar to that of a flag used by the Nazis.

In any case, both groups, especially AntiFa are using tactics that the Nazis used back in the 30's, 40s - book burning (statue toppling today, but also the cancel culture of 'burning' books and movies that they dont like) ; stopping freedom of speach, going after religion, being violent etc.
