I think you’re missing several things. First, if the phenomenon is accurate, and it is, then the burden is on you to figure out how to stop getting played. Don’t ask other people to solve your problems. Recognize your problems, and then work to solve them directly.
Second, the spoiler effect doesn’t exist unless you’re in a swing state. But how many Americans were told that they have to vote for Harris or they’re supporting Trump, when in fact their state was nowhere close to 50/50 so realistically they could have voted for anyone?
Third, there is no single leftist community. There are many different leftist communities that overlap and agree on various points. Also, you’re suggesting that leftists are idealist, but that’s not the truth. We all recognize the current situation, and we’re trying to make a better one, but you’re not. In other words, your cynicism has caused you to throw in the towel, and to accept the current reality as permanent, unchangeable, it sucks but there’s nothing you can do, and that’s certainly true if you believe it.
To be precise, we have no idea what evidence was collected or what it shows. All we know is what the cops said they found, and cops are notorious liars. Just ask Young Thug or Karen Read.
We can assume some of what the cops say is true, but the challenge is that we have no idea which parts.
