That was speculation of where the fledgling #BirdsArentReal movement could end up, but I'm really not serious about my criticism of the meme.
As a sibling comment to yours pointed out, true believers of things like a flat earth are an extreme minority and I'm not particularly concerned that a parody conspiracy theory will cause much harm. I doubt the few true believers will be burning chicken coops any more than flat earthers are blowing up globes. (I really hope I'm not wrong about that, I do like chicken quite a bit).
And we, as a society & individuals, can't and shouldn't be 100% serious about everything 100% of the time. We should be able to laugh at things, even very serious things. For example I find it pretty funny that some Russian tanks are being abducted by Ukrainian farmers w/ tractors. I can also see how deadly serious it is: It's not like they're just a few viral videos made by influencers, it's everyday people like farmers trying to take deadly resources out of the hands of an invading army.
I like your points about the necessity of humor and i think its the only way to the future for us without mass psychosis and cultural schizming. When biomorphic-engineered bird-drones can fly autonomously, and pigeons have been carrying IP for the ruling class for thousands of years, we are going to need some comedy to settle the #birdsarereal issue
