This is a good idea. Maybe we could protest in the streets like BLM and Antifa did (without doing anything illegal), because they got governments to defund police. And protests have caused great change in many areas of the world.
If most of the the men in the world are secretly incel, then we do have the numbers on our sides. Imagine if 80% of all the worlds men took to the streets to demand the banning of tinder and other dating apps.
And honestly, we don't even need governments we just need to get the app stores to ban them. Maybe an online petition would be a good place to start. If there are any brave incels we could go on news outlets to talk about this, and ideally even join forces with feminists and female phycologists (which are the most over powered as far as ability to change culture).
Because online dating is physiologically damaging to everyone. Women may choose to be used up by infinite chads, just like drug addicts choose drugs but many of them might be happier and more fulfilled in longer more loving and committed relationships. But that's not possible if they have a buffet of gigachads at the swipe of a finger, just like it would be impossible for many people to stay sober if when they walked down the cereal isle at the grocery store there were honey nut cheerios laced with crack cocain and morpheme.
Online dating is damaging to society, we just need to perhaps infiltrate organizations that have more political influence than incels, such as feminists, phycologists, media, and push back against it. This may honestly be the only way many of us could ever find love, if we can collaborate, infiltrate, and destroy this beast.
