Black Lives Matter protesters disrupted the inside of a McDonald's and got into a confrontation with a manager. I'm not sure about you, but if people disrupt me when I'm eating lunch or at work, and I have nothing to do with their cause or protest, then I'm certainly not going to listen to anything they say, nor will I support them.
Do not bother people who are not connected to, or have anything to do with, said protest or cause.
Leave people alone and stop being a nuisance to society, and maybe others will start to support you. All this rude disruption and harassment of people in public will make people dislike and not listen, so it's completely pointless, rude, and arrogant.
