Voting vs other actions isn't a dichotomy - you can vote for the lesser evil to buy time, AND do the things that will make a real and lasting impact.
In our current system though, red team vs blue IS a dichotomy - using your vote you can nudge the counter a tiny bit closer to one side or the other; or opt out / vote third, which both equate to doing nothing and letting you're countrymen choose for you, but the potential results are the same: red or blue.
So, you can use your vote however you want, but I'd recommend pitching that nudge away from the more blatant Nazis. ...but also build those guillotines for use against hostile actors regardless of party.
What folks 100% should NOT do though is vote and then consider their 'civic duty' satisfied, which is ofc the sentiment OP is aimed at.
