I think demanding a better system is a good thing. A lot of the young people feel rightfully disillusioned with what has been handed to them. Are there plenty of spoiled college kids actually doing nothing? Yeah.
As for culture war nonsense regarding gender or whatever else. I don't care. People can identify however they want. I believe in this as an essential freedom. But I believe you should just as much have the freedom of expression to say you don't understand it. I don't understand it either. I won't pretend to understand it.
Demanding a better system without living out that system yourself is irrational. That's the main problem, they demand a better system but don't actually live that out. If they did, they would be working their asses off starting successful businesses then paying back the profits to their local communities. They would be training at the gym every day for the strength to protect and uplift the weak.
But they don't do that. They only scream and destroy, to then go home and goon all night and indulge in insane discussion forums such as Reddit. They don't actually live out what they profess to believe.
At least the old school Leninists were hard working men who were shafted by the system they fought against. The leftists of today are just effete bourgeois.
