You specifically went looking for instances of violence at the protests, and you found a couple. This is the very definition of confirmation bias: you have a conclusion, and then went looking for supporting instances.
You didn't look for data about how much violence there was relative to other protests, or injury statistics, and you certainly didn't look at comparisons between right wing and left wing violence. You started with the conclusion you needed. You need the protests to be violent to confirm your world view, so you went looking for some instances to try and support your conclusion.
However, nothing in your paltry few examples refutes anything I said. Given the vast numbers of people participating in the protests, and the length of them, they were remarkably peaceful.
On the other hand, a tiny fraction of that number of right-wing violent lunatics concentrated in DC on Jan 6 and in one day committed more violence and slaughtered more law enforcement officers than at all the BLM protests combined. BLM protestors want police officers to stop killing people, the Jan 6 insurrectionists came looking to violently overturn the results of the election, and are feeling emboldened to commit more violence in the next week.
I hope this helps you stop and think.
