People who sympathize with your cause wont want anything to do with you after a display like that.You're right, T2 - the protesters went way over the line. Cursing gains nothing - other than to weaken your argument. At the point the officers came to take them into custody, submit and wait for your day in court. You'll gain NOTHING by trying to provoke officers that will do "your side" any good.
Although I might play along to meat that chick in the red shirt...I may have mis-spoke. There was a guy named "American Patriot" in the comment section. I though he was affiliated with the website.
Several in the video could have gone for interfering or disorderly conduct. No gun owner I know would want to be represented by such a group of out of control "protesters". Another case of "advocates" being the worst enemy of the 2A.
Before its over we will have legislation banning OC of long guns thanks to morons like these.
