One in a thousand in attendance does not know what a Israeli flag looks like. Almost all don't know the difference between the confederate battle flag and the British Union Jack. These demonstrators are hired political activists, jobless, many homeless, nonproductive idealists. Plain language, dysfunctional, morally corrupt, drug infested deadbeats. I new the same people in 1967, grew up with them. Weak minded college kids on dope, led by communist social revolutionaries that had taken over Universities. San Francisco  in 67-8 was a disease infested human garbage dump. Created serial killers, AIDS, drug funded Ca. politics. The wonderment of it. Take down some monuments? You have no idea what they want. Private property, ability to associate with who you want, or not to. Children belong to the state, not parents, limit of travel. Think about it.
