This is a question that I've wasted a lot of fruitless rumination on. Is it actually possible to exploit memetic power on the side of justice? I haven't answered this question yet, to my own satisfaction. There's a major problem: lies, indisputably, are more memetic than truths.
What's that saying? “A lie can travel halfway around the world while the truth is still putting on its shoes”, which apparently derives from Jonathan Swift and not from Mark Twain as commonly supposed, q.v. https://archive.is/T4JZb
There's an excellent reason why: deceit provokes comment. If you came across "sin θ / cos θ = tan θ" spraypainted on a concrete wall, you might smile to yourself and say there's a nerd in the neighborhood, or you might not understand what it was and think of it as only a curious graffito. This item isn't devoid of memetic value but it's...slight. Under the same circumstances, if you came across "sin is Hunter Biden's laptop" spraypainted on a wall, you might feel disgusted enough to do something about it. Lies and hyperbole about Hunter Biden's laptop are irritating partly because the lies are so obviously manufactured for mass appeal. The more outlandish the lie, the more comment is provoked.
Hence most reasonable persons, I would guess, stay away from memetic cesspits altogether. I've never been into the deeper places (4chan and its gazillion spinoffs, for instance) and I only lightly brushed the surface of SomethingAwful's memetic culture, so my chief exposure has been through Twitter, and that's bad enough for anyone. But I've always been reluctant about conceding this field to the enemy. I feel the same way about memetic literature distributed through physical means, such as fliers and pamphlets. Extremist Christians and other cultists dominate this space and it doesn't seem like they can be bounced out.
Or can they? That's the question I'm asking myself. Is it possible to meme on the side of justice?
It's a dangerous business because memetic popularity also means taking a flying leap down the road to perdition. To be popular is to be ensnared, tempted by the system's offers of help. "First I'll become a YouTube star, then I'll spread my message!" is an occupational hazard of breadtube celebrities. "Corruption" isn't just a buzzword, it's a real enough danger, and corruption has never been easier than now. There are so many technological interconnections that furnish a myriad pathways for the spread of corruption.
At worst you get stuff like...Barack Obama's memetic HOPE poster. I don't detest Pres. Obama exactly but he was a crushing disappointment partly because he really did seem like hope, once. After eight years of George W. Bush, maybe the nation was actually returning to civilized values! Unfortunately the ad campaign was cynical in the worst way. It's never a good idea to place all your hope in a single human being, whoever that person is, unless there's really nobody else around.
But surely there's some middle ground here? Some acceptable usage of memetic stuff? It rather goes against my nature (for some reason) but I can perhaps think of positive examples. Nothing wrong with Buddhist prayer-wheels per se, for example? Those are reasonable, right? That might be considered "memetic". But I'm also thinking of the left-handed uses of memetics, like...memetic poisons, in analogy to biological poisons or catalytic poisons, substances that deceptively mimic the structures of beneficial molecules and stop reactions from happening.
