What I think that fails to realize is that so much of our technological world is defined by political decisions.
Failing to be aware of them and engaged in them (to a reasonable degree: it's a slippery slope) cedes those decisions to people who are technically ignorant.
In my country, there have been pacific protests about housing. They were faced with police brutality, but this only increased the people protesting and making demands. Some politicians initially said they wouldn't change policies, but seeing so many people involved, now some are changing their stance.
Politics have gotten really divisive, but ignoring them is not the answer.
Since everything has some political lens and the same repeated talking lines continue, and go way off topic. The discussion becomes meaningless.
So that's my reason. You can even say that these are extreme and must be destroyed, that makes the point more clear on why the flags happen. It's not bots, its people.
