One: Marxists go all the time to protest in an effort to recruit for DSA, PSL, FSRO
Two: as I already said earlier in this thread to you Marxists and anarchists spend their time in local organizations that actually affect their community.
I spend my own effort pushing for local organizations and donating my own time and money to those local organizations which is sure of Hell a lot more effective at bringing change than voting. This is a key and core strategy of both Marxism and anarchism.
The fact that you don't know that indicates that you should pick up a book.
