If Shinran were alive today and happened to be on the playing field (or basketball court or baseball diamond, you get the picture) as the National Anthem played, do you think he would take a knee? And can you please elaborate on your answer?
Shinran would probably take a knee; he was a radical in his own way. He was definitely not a political person, but he would be angered by the U.S. president trying to make political points at the expense of a racial minority.
Not standing for the National Anthem is not about disrespecting the flag and not about showing disrespect to the principles of democracy. Rather, it is about remembering that justice has not always been equally practiced.
He was definitely a person of the ordinary people and would have empathy with Black Lives Matter.
