I have mixed feelings about violent protests. Ideally, there should be no violent protests, and reasoned moral arguments would persuade people to change, but we don't live in a world governed by philosopher kings.
Every major movement from the suffragettes to the civil rights activists needed to use violent tactics to pressure the state into making the concessions we now take for granted.
Violence does solve problems but only rarely and when done intelligently. Unfortunately, violence is chaotic, and even the most calculated violence causes collateral ruin, solving one problem just to create more. A smart BLM leader would recognize the importance of violently confronting the police and the state to achieve her goals, but the rioters destroying innocent people's lives would be inevitable. The rioters themselves are just opportunists out to loot stuff or take revenge against the white man. So if you were a BLM leader, you would have to try minimizing the rioting and other dangerous idiocy while assuming responsibility. Way easier said than done. That is politics outside Twitch.
That being said,
@Table Country is right. The brat needs to get her ass whooped and be sent home to her parents.
