It sounds like an interesting strategy, and might be fun if that’s what your about, but I doubt it’s very effective

I've been doing this since 2016 - the only thing the alternative strategy is effective at is to ensure it's users suffer endless burnout.

As you can see... I'm still very much at it.

I think the risk of it backfiring is probably too high to see a very good return on your effort,

Backfire to what? Simply flowing along the "liberal-to-fascist" pipeline like they were doing anyway?

I expect no "return" here - this is not a business. I don't treat people like "political assets" that has to be gaslit into doing what this or that faction of the political establishment wants at all costs - here on lemmy.world, I leave that shit to the "vote blue no matter who" brigade.

but I could also see the toxicity of the cynicism required to maintain the strategy decompartmentalizing and seeping into other parts of my life

Not really... my irritation with people who think they can "vote" fascism away is short-lived and skin-deep - it's very hard to stay angry at people when you know exactly how the politics that have been drilled into their heads got there in the first place. You might just as well stay angry at people for catching the cold.

potentially causing me to alienate my friends and family as well as affecting my mental health.

The group of people privileged enough to be able to convince themselves that politics is simply a spectator sport they can opt out of whenever something better is showing on the other channel is shrinking by the day - the friends and family I've lost to the far-right had very little to do with my behavior, I'm afraid. It's almost like liberal politics primes people to either lurch towards the right or merely acquiesce to it after a smidgen of ineffective protest - and I have a hunch that's no coincidence.
