Funny how white starts all kinds of race threads here but MAGA12 is the race troll.
“What to the American slave is your Fourth of July? I answer, a day that reveals to him more than all other days of the year, the gross injustice and cruelty to which he is the constant victim. To him your celebration is a sham; your boasted liberty an unholy license; your national greatness, swelling vanity; your sounds of rejoicing are empty and heartless; your shouts of liberty and equality, hollow mock; your prayers and hymns, your sermons and thanksgivings, with all your religious parade and solemnity, are to him mere bombast, fraud, deception, impiety, and hypocrisy - a thin veil to cover up crimes which would disgrace a nation of savages. There is not a nation of the earth guilty of practices more shocking and bloody than are the people of these United States at this very hour.” -Frederick Douglas
White boy, Crispus Attucks was a slave who would not have been free after the Revolutionary War. So the OP is correct in saying that blacks should not wave the flag or bow to the Anthem. And the fact that a black slave died first for the freedom of whites should make you guys understand that you owe us gratitude.
