If they keep hammering at it, for years and years, and focus on kids, I think they will succeed to some extent. How many mindless SJWs were sold on innumerous idiocies because it gave them a feeling of smug righteousness? I think bugfeasting will be the same for them. "You're not eating bugs? Nazi! You eat bugs? Me too! *smug beaming*"
Same thing happened in the 60's, though.....
Kids left college convinced the virtues of free love, quartz crystals and psychedelic rock could cure the world's ills, and rapidly gave it up because not only did it not fix the world, it didn't absolve them from the need to get a job, or pay their bills, and their resolve to leave grubby capitalism behind and be one with nature and live in a commune died out after two weeks of living in one, and learning the hippie master in charge may have publicly said he was against Vietnam, but in private owned shares of McDonnell Douglas.
It's easy to say you'd love communism when you're young, dumb, and convinced that you can change the world, and yes, virtue signaling is a great way to get a personal high, but more than a few years in the "real" world will wash that enthusiasm right out of them, so much so the first time they actually have to eat one of those bug bars, they might smile while they do it, but 90% of them aren't going to ever eat a second.
The donors who keep funding this shit are so out of touch and disconnected with reality that they think the masses are too stupid to not fall for it.
The media elites conflate the disinterest the average person has with them and their message/narratives with obedience, and vastly overestimate their ability to control the masses. When they publish these articles, the fact most people roll their eyes doesn't register. Nor really does the fact that the public doesn't immediately line up and obey.
All that really gets through to them is "There wasn't a riot, so they have successfully been brainwashed to not oppose us! Nudge them a little more and we win!"
That's why the populist rejection of globalism was such a shock to their systems, it really did seem to come from out of the blue, they couldn't see the 30 years of eye-rolling that lead up to it, they arrogantly thought they were in control only because the peasants hadn't openly revolted.... until they suddenly did from their POV.
