Racism at protests

My roommates and I were helping our protesters in peace. I am an Asian woman and my roommates are Caucasian and Multiracial. Out of nowhere, an older white male driving a truck stopped in front of us and started harassing the protesters. He started using some harsh and negative words and got into a confrontation with one of the protesters. They were arguing for a good minute and then the guy in the truck threw a bag of trash at the protester and drove away. And to be honest, there were multiple incidents where I was personally attacked by older white women in line to the grocery store. It will not go unnoticed. It will stop.
