Okay, but that quote doesn't support the conclusion that engaging in harm-reduction via voting is instead a bad thing. In fact, it doesn't even argue that your vote doesn't matter. The only thing it suggests - and I can't even say "proves" here, as your own disclaimer brings the validity of this study's conclusions into question - is that mass voting doesn't result in policy change from the major parties.

Voting for the party that is going to bomb brown people, rather than the one that is going to bomb brown people, round up locals who look too brown, and de-legitimize LGBTQ+ peoples of all demographics, is harm reduction worth engaging in.

I eagerly await the total failure of capitalism as much as the next socialist, but I am not condemning local minorities just to win some form of imagined moral high ground.
