Lou Marconi, where are you getting these ideas? State, local, and federal representatives of the government all actively attacked MLK. Police forces literally attacked him and others. He was repeatedly accused of disrespecting and attacking the country. Protests he supported included walking down the street, sitting a restaurant, registering people to vote, and _not_ taking public transportation.
Tell me, prior to Kaepernick’s protest, whenever you heard the national anthem, did you stop what you were doing, stand at attention, and remove your hat? What about when it’s on TV? Do you do that now?
I asked before, but I’ll ask it again: are you disturbed that Kaepernick started protesting at all or are you disturbed by how he protested? What, in your mind, would be a valid protest that you would approve?
You may feel we should punish people for not standing for the national anthem, but only fascist dictatorships do that. Check out China for example. https://www.nytimes.com/2017/11/04/world/asia/china-hong-kong-national-anthem.html
