Escalating a conflict is not necessarily a bad thing. It gets the attention of the entire nation. And it doesn't matter that you don't win any sympathy from pundits, politicians and the media. Its not supposed to. Its meant to expose exactly how the system works. That a capitalist society doesn't give two shits about the systemic oppression and mistreatment of those who have little or no value to it. But as soon as property is destroyed, they're willing to use any force necessary to get it under control. And that force is excessively violent. The people governing you would rather murder you in the streets than have a Walmart looted and burned down.
Using grandiose terms like a "capitalist society" does not make your assertion true. You forget there are real people who work at these places that now have no place to work because their businesses were burned to the ground. You are making the claim that destroying lives is acceptable because you are angry. I vehemently disagree. If this was a slave revolt burning a plantation to the ground, I would 100% but this solves nothing and does nothing. The impact of George Floyd's death was shown the world and and outcry of support came because they saw the system broken by how the police acted. No one in their right mind said "Hmm wow they sure are looting a lot, they must be really angry and the system must be really broken, better let them keep doing it". Its apologist nonsense.
Then you wouldn't mind sharing the alternatives? What changes have civilty brought? People have been protesting peacefully and trying to get attention and political action for decades. And nothing has changed. People are desperate. They're literally being killed without any repercussions. Telling them to play nice so we can go back to ignoring them is privileged beyond belief.
The system IS changing, its about having the political will to do something about it. When the LA riots happened, did police brutality end? No. What did MLK advocate for exactly? Did he demand a peaceful protesting that marched for black people's right to vote, that was successful or did he say to burn buildings and riot until the system bends to their demands? My alternative is to document and record. Show the people at large what its really like to be a black person in America when the police are involved. Its not rioting when you are angry, its forcing the truth into people's faces for as long as it takes.
