1: You are "poking the bear" because everything you post to this community is pursuant to getting Harris to lose the election, either through pro-PSL or Green articles (via the Spoiler Effect), or through explicitly anti-Harris articles. That's the pattern behind your posts, it obviously doesn't matter how reputable a source is to you so long as you can flood Lemmy with this content. "Take it up with them" is a copout for your behavior because you choose to post their articles here.
2: You clearly don't know what astroturfing even means. What could pro-Harris posts even astroturf for?
3: Repeatedly posting articles about getting Harris to lose the election and arguing in bad faith in defense of why that's actually good for advancing socialism in the US is toxic because it's literally incorrect. And when pointed out, you say you don't actually think a second Trump term would be all that bad for you. It's patently obvious what you're trying to do on here, you're trying to get leftists on board with neo-fascism and accelerationism to enrich yourself.
They're useful tools, as is the Lincoln Project, for example. Once the existential threat in Trump is gone it'll be back to business as usual and their MO will be "oppose meaningful change without enabling a monster to take advantage of us again" again in no time. Trump is such a unique and unhinged threat that they resent what they've created, and in an equally unique moment of self reflection, created the Never Trump movement. But longtime allies to leftists, or even liberals for that matter, they absolutely are not. There's no ambiguity around it.
