Marxists have been opposed to electoralism since the time of Marx, and not simply around election season, but year-round. It's more that liberals seem to notice revolutionary rhetoric from Marxists more around election season, because that's when liberals are more likely to tune into politics. This meme doesn't actually do the Marxist position any justice, and it misidentifies Marxists as the cause of voter apathy, rather than the actual source: the widespread feeling among voters that voting doesn't actually bring change.
We understand that the state is ultimately a product of the class struggle of society, determined by the base economic structure. Reforms and concessions are not won at the ballot box, they are won through organizing on the ground and directly fighting the system, forcing it to concede. The Stonewall Riots were the catalyst for progressive change, not a change in heart in the ruling class. Same as the Civil Rights Movement, where Dr. King was assassinated as he began pivoting not just from anti-racist agitation, but towards the Poor People's Campaign, a growing socialist movement. It's why the Black Panther Party was infiltrated, and its top leaders killed or imprisoned.
This meme makes it seem like Marxists are some omnipresent movement terrifying liberals into withholding their votes, but the truth of the matter is that political apathy is high across the board. This isn't an inorganic reaction to Marxists finger-wagging people for voting, it's an organic reaction to the fact that both mainstream political parties do not represent the working class. This is understood across the political spectrum. Especially considering the electoral college system means that a huge portion of votes that lie in solidly red or blue states do not actually make a difference, we have to return to how we actually can gain change.
Learning from past struggles, we can see that in every major concession, struggle is what earned reforms. The point isn't that voting for the DNC magically harms the movement, the point is that treating voting as your primary or sole political outlet means no change is possible. The electoral theater is treated like the single most important thing anyone can do politically, but history shows that change has only ever come from the people fighting for it. This is why the age-old adage is
