You say this, but think about all the posts you've seen on this very forum (particularly in P&R Funnies) expressing a nihilistic view of the choice between our two parties. All those comics where the donkey is like "I'm not trying to kill you, but I'm going to sit back and watch idly as the other guys do, rather than do anything to stop them." Well, that attitude is even more prevalent among the younger set. One move that majorly pisses them off could be the difference between staving off critical voter apathy for one more election cycle or majorly blowing it and handing the next election to Trump.
Napster dying didn’t throw an election and neither will Tik-Tok.
While a lot of us (myself certainly included) whine and grouse that Biden and most of the established Democratic leadership are worthless neoliberal shills; we also vote because yeah the difference is between being punched in the balls and being fed into a woodchipper so there’s easily a less worse option.
