I agree with you Mr. Strickland has a history and is a well known  agitator in other protests.  There some indications that Mr. Strickland has a large number of defenders for all his actions from 'white supremists' Google his name and you can find the blog where 'white supremacist' are congratulating him.  No one that's rational supports 'white supremicist' they're all on watch lists because of violent behavior.
