I agree, the probability is high that "something is going on". How much of that "something" can be attributed to malice, and how much to simple incompetence, is a question that I can't answer. If I was asked my opinion - and I know I wasn't - I would say that Pelosi and Schumer are malicious, while Biden and Harris are incompetent. Hillary Clinton is self-proclaimed royalty, AOC is low IQ, Obama is opportunist. So we have a real mix of talents here, that all add up to a disaster.
I have a suspicion that there are people who are trying to harness all these politician faults into a force to get their way. No proof of that, just a suspicion. So I believe we do kind of agree on several things (not trying to put words in your mouth).
However, "It turned out it was a poison that was meant to kill off the population" is a leap too far. Not supported by any evidence that I am aware of. This is something I would expect AOC might say if she were on the anti-vax side. I don't want to come down on AOC too hard. You gotta love her. Every declining political party needs a parasite gnawing at them from the inside to speed things up. AOC, and her squad, are those parasites. I hope the Dems continue electing them. The gift that "keeps on giving" to Republicans, year after year. Anyway, the point I was making is that AOC and her squad are not necessarily malicious, they're just idiots. Useful idiots.
