When we scratch a little a main motivation for this behavior is always greed.
Most of the time, somebody, somewhere, is being paid for recruiting and directing the anger of dumb people against the desired target. Just last week there is the scandal of Tenet Media [1]. With a team of US youtubers being banned for Google for allegedly accepting 100k dollars a week (a week!), directly from Russia, to spread Kremlim propaganda from Tennessee
Is hard to fight against this people because they are just a spendable, fully replaceable, part in the plot. Remove this people and other will come to fill the gap
But, stop the money transference and things will change. Hunt and block the bank accounts of this people until a review was done. My bet is that people suddenly will stop trowing soup and gluing their body to invaluable pieces of Western culture, or leading people to assault the capitol in a clearly coordinated effort, or causing chaos on trains, or starting wildfires that cost everybody millions.
