Of course the U.S President of the United States, Donald Trump, should have ceased reactionary tweeting when he took office at the White House. Of course he should not have waded into this anthem kneeling chicanery enacted by NFL players through twitter. However; he is entitled to have an opinion with respect to protocols, conduct, and assembly of Americans in witness to the ceremony of the country’s national anthem.
Americans exercising their civil liberty are entitled to their opinion regarding each others’ conduct. If a citizen has a grudge to bear against their country, they have the freewill to express themselves within their law abiding rights. Each American has the autonomy to choose which way they wish to fight their civil battles within their rights. I suspect that many Americans lacking weekly television exposure while administering their own rights for justice would rather see NFL players take their grievance(s) to the appropriate forum for resolution rather than grandstanding in front of folks enthusiastic about watching some football.
I, personally, stopped watching football in 2014 upon learning of an NFL player beating his wife in a casino elevator. There was much ado about whether the player should be suspended by the league or not. The story line had morphed from the strategy of defensive alignment, pass protection, finger tip end zone catches, and fourth down late game conversions into a gong show about the conduct of privileged elite players having difficult managing themselves.
