Right now in the UK people are protesting an authoritarian anti-protest bill. How many are out there because they were outraged by it? What if they were at home, happily following their respective hobbies instead? If no one ever speaks up, what prevents society from sliding towards fascism / 1984 / etc?
And the great rhetorical weapon of today is framing what you don't like as a pathology of those you disprove of. They aren't doing what you want? They're dysfunctional or sick. They do something you dislike or value something you don't? They're infected or addicted. Etc.
An example. Being hungry and finding high-calorie food is, in our natural state, a very important mechanism for survival. Our tribal ancestors wouldn't have survived all the famines and periods of bad luck or bad weather if we weren't programmed to seek high-calorie food.
Unfortunately, in the developed world of 2021, we have so much cheap high-calorie food in our lives that blind obedience to the ancient "gorge yourself!" impulse is killing us.
The same applies to outrage. Twitter is an outrage mall, with outrage screaming at you from every shop window there. It is not in anyone's interest to buy it all.
The police have been really accommodating of protests. It’s an incredibly fine line they have to walk, between the fairly soft rules of engagement, the right to protest, and the COVID restrictions.
