Ostentatious patriotism always struck me as being rather over the top, the whole hand on heart bit especially, but it’s their country. That said, what is disrespectful about kneeling? If the players sat talking or posting on Facebook  or thumbing their noses at the flag, I could see why some might be miffed, but taking a knee? Given the current situation in the US what with hurricane damage, wildfires, the odd riot, trillions in debt and a gridlocked Congress I should think Trump would have bigger fish to fry than a few players taking a knee in a respectful manner to protest injustice.
