The great thing about this topic is this exact argument has already played out in a very recent historical example. You could, and many people did, make this exact argument in 2016, and it produced the very decisions we're talking about. And now, evidently having not followed that thread of cause and effect at all, you're back saying the same argument again.
It's precisely because SCOTUS appointees lock in long term consequences that impact multiple future administrations that they are important, and a clear example of where differences in power lead to different outcomes.
This has always been the obvious weak spot in the "both sides are the same" argument. The only answer anybody has come up with is to constantly change the subject. Which is the tell.
Not only did they literally not say that... actually no, let's just pause on this. This is so confused it's actually kind of amazing. Explaining how first past the post works is not saying don't vote third party. You could still like a third party the most independent of electoral concerns. And explaining the strategic reasoning for choosing one of the two major parties isn't the same as saying you "should" vote for them in a moral sense.
Voting to enact a ranked choice voting system isn't the same as voting for a third part. You could want rank choice voting even if you favored one of the two major parties but don't want them to lose narrow elections when they might be the winning coalition. You could hate the third party and still want rank choice voting. You can both support a third party and support rank choice voting and understand that they are two entirely separate things.
And I suppose the cherry on top is you referred to them as "you" like it was a single person in a comment chain where it's three comments by three different people.
Truly a magnificent multi-layered piece of confusion, chefs kiss, five stars, two thumbs up, etc etc.
