seriously?
Yes, seriously. What’s your source on it?
I don’t think I need one, It is pretty obvious. What do you think would have been the reaction if someone tried to protest during the National Anthem in the 1950s or during WWII? I think they would have stoned the protesters(not that I am saying that what should be done or that I would want to do that).
Maybe in this years, when America was in its first anti-communist hysteria, but there were a lot of protests in later years, even at sporting events sometimes.
