If you don't vote, don't complain about the outcome. It is de facto approval with the result regardless of how one spins it.

If you believe the system to be flawed there is no hypocrisy in not engaging with it while simultaneously denouncing the outcome. For instance, I am vehemently opposed to the outcomes produced by a defacto two-party system so for my entire adult life I have exclusively voted for 3rd party candidates on principle. In practice this is akin to not voting at all. I have been accused on multiple occasions of failing to prevent the 'bad' two-party candidate from winning by 'wasting' my vote. Nevertheless, I find it well within my wheelhouse to cast critique.

Well, as I said, your opinion is one I have heard before. If you have some deeper reasoning or insight to share I would love to hear it.

I think you're totally right if they're in a swing state, but it's less clear otherwise.

What if you were disenfranchised? This happened to me before, due to residency and main-in ballot rules. This may be a significant number of non-voters.

Your intentions don't matter, only your actions. The fact is that about two thirds of the population voted that they were okay with a Trump presidency, and slightly less than that with a Harris presidency.
