It's pretty simple. Pose the question. Make them think about it, even if it is brief. I see young adults with masks walking around everywhere with their hair shaved on the sides, tattoos, and pants sagging.
When they stop because I'm not wearing a mask, I ask them if they would pull their pants up if a politician said they could get a cold. Then I ask them if they would turn their music down to avoid a potential rash.
Young people are still defiant, but they might need to be reminded what those masks really represent. Everyone else has one. These are the same kids that are spreading STDs, which are so much worse than anything seasonal, and they STILL fuck like rabbits. Every little crack in the Democrat brain lock is progress. You never know what you can get going with a few well placed questions. Sometimes people need to be reminded that they arent cattle, and the best way to do that is to create doubt, which is the ultimate death of totalitarianism. That's why Communism is always a few (thousand) murders away from paradise.
They will do whatever they're told to do In exchange for all that free stuff.
Which is why it works to use oblique methods over direct ones. Telling people to take the mask off, because it is a fraud, is less effective than saying it makes them look like a scared little bitch.
For younger adults specifically, appealing to their sense of cartman style "I do what I want!" Is a better method. Maybe its specifically for "urban" demographics, but these are the same kids with so little regard for others that they deliberately cause problems when ANYONE tells them to do something. The seed is already there, since almost all young adults are rebellious to some greater or lesser degree. We can build on that. We cant stop them from being guided by their emotions, but we CAN point out other things for them to attack.
They are like a river flooding your land. You can build a dam to block it, but it wont last long. You can try sandbags and walls around your land, but they dont last long either. The smart move isnt to fight the river head on. The smart move is to divert it away from your land, which is a permanent fix.
