Things change as times pass.
Leftism used to be a thing in france, until the 80s where they seized power and showed their true face.
Or maybe more realistically the 90s, when what they did became actually visible to most.
Some people still don't realize that even today though.
I wouldn't blame young people for having wanted to believe in it - errare humanum est.
But yeah, now is certainly the time to wake the f up if you still didn't.
