I know I've asked this jokingly. But if you want to know the psychology behind this there is an actual answer.
Here is the problem. The anti-mask trolls are narcissists and narcissists need supply. And that supply is drying up in the real world.
Yes, they bullied most of the population and the government out of commonsense public safety health measures, but that created a new problem for them. A lack of in person people to bully. Because so many caved to peer pressure to stop masking and so many others opted to protect their health by avoiding indoor spaces (staying home from events, ordering online, etc).
And now with the majority out in public unmasked they don't know who to pick on. With the nice maskers now preferring to stay home more there is a higher chance the person they pick on will be another bully. Picking on a random person has become more of a gamble.
But they still went out for their fix. After all there are low paid in person works to bully. Except when the anti-mask trolls got to their destination, they found two things.
One: These workers have now become irreplaceable because thanks to lack of COVID measures there aren't enough people willing to work bad jobs for low wages. So, basically the workers don't care if they are unhappy and complain.
Two: Due to the difficulty in getting low paid workers, the worker they hoped to bully had been replaced by a machine. Congrats the checker they used to bully is now themselves! The self-checkout can really care less if you yell at it. Nor can you get it fired.
So, back to the internet they went looking for victims to get their supply fix. And this is where I give you advice-don't feed the trolls. Report them, block them, print screen and send it to their employers, but truly do not be their supply.
