I was at that protest in Berkeley and your claims are exaggerated. I've written here extensively on what was objectionable about the speaker's visit there and why I think the protests were justified. You should consider that a supporter of that speaker shot someone at a similar event only days earlier. If you are concerned about violence as you claim then I think rather outranks some broken windows and a burnt-out generator.
