/r/Conservative and its “brigading” complaints

Given that nearly every post is for “flaired users only” and that anyone who has ever dissented on open posts is banned, do they really not understand that up/down voting is the only way for everyone else to participate in their posts?

Every poster seems to complain that their thoughtful contributions on why Nazis are not really Nazis or how tariffs will reduce prices, get downvoted like it’s some sort of conspiracy.
