You don’t need to. I’ve run the numbers elsewhere but if we assume 100% of your dating pool are women and 50%-ish are liberal, even if only half of them participate it’s going to put pressure on men very quickly if they don’t want to be alone.
Now we know those women aren’t spread equally so this movement isn’t going to be consistently effective everywhere. But in places like Texas, it would mean most of the major cities harm Republican men seeking relationships/sex.
And taken one step further, this creates a child shortage if done for long enough. Even just 10% of women deciding not to have kids will have a big effect.
People worry about conservatives just having more kids but realistically they work lower end jobs and don’t have money for that. Imagine raising 3-4 kids in this economy, not many will do that.
