That's a circular argument. Drag asked you how voting props up the electoral system. You said "well how does propping up the electoral system help?" Drag agrees that propping up the electoral system is bad, but drag has not been told a reason that voting is that, except that it's supposed to be a symbolic loss. Drag doesn't care about symbolic losses, drag cares about stopping Trump from bombing the West Bank. Drag cares about Palestinian lives much more than symbolic complicity. Drag still wants to hear a practical reason why voting helps electoralism.
Drag still wants an answer to the question you think drag should have asked. Drag doesn't think that detail is worth delaying the actual conversation for.
Your answer was that it's a bad symbol. If drag thinks the only reason not to vote Democrat is because it's a symbolic admission of defeat, is drag understanding your argument as you wish it to be understood?
The physical reason not to prop up the democrats is that the democrats are leading the US to the end of the world, just like the republicans, and legitimizing their rule makes leftist organizing more difficult.
Drag already asked how voting for the democrats legitimises them, and you didn't answer except for a symbolic reason. Drag wants a practical reason. Do you understand drag's critique? You gave a "practical" reason made out of symbolic reasons. Drag wants a practical reason made out of practical reasons.
I already answered. Voting Dem perpetuates Dem rule, if Leftists are pushed to vote Dem and see it as activism then the Dems take advantage of that and portray voting Dem as activism. Feeding the electoral system by voting for either dictatorial establishment party maintains their rule and legitimizes the system.
Drag doesn't care who sees what as activism. Drag cares if leftists are doing things. Drag cares about vandalising cars, and reducing animal consumption, and making bike lanes, and bothering oil companies, and making the police feel scared, and giving hormones to trans people, and ensuring abortion access, and open source software, and getting social media out of corporate websites, and giving homes to homeless people. Drag votes too. Drag doesn't believe voting stops drag from doing all those things. Drag doesn't believe voting stops anyone else from doing those things either.
Drag thinks you are afraid to admit defeat. But there is a class war and there has been for ten thousand years. And wars have battles, and some are lost. Right now, leftists lost the battle for the US electoral system. We will admit we have lost, and then we will band together and win. Drag doesn't think we can win if we pretend we have already won. Drag doesn't think we can win if we pretend the electoral system is on our side. Drag thinks you are pretending the electoral system is on your side. Drag thinks you are too proud to admit that the system can force you to pick between only bad options. Drag thinks you are scared of the system having so much power. Drag knows the system has a lot of power, and drag knows we can still beat it. We will do what we can with defeat until victory is ours. And we will fight on all the other battlefields too at the same time.
