Well, I participated in Vietnam protests. So, when you say it's not true, you are saying my own experience is not true.
Camping wasn't a formal of protest in the 1930s. I was a matter of necessity.
When you put people in the streets, it gives a chance to see the size of your opinion. It's also good for media to advertise that opinion.
Now, all you see is nice tents and threats to Jewish Americans. No matter who you are, by occupying a public or private space you are begging to be moved.
Protest the way you want, but it doesn't make too much sense to occupy. Won't get the, sympathy of the nation it seems to me.
