Racism is real. Racism is stupid.
On the other hand, if we look at how many players in the league are from Canada (almost half) and Europe (over a quarter) it seems out of place for the players to do things the way that the other leagues have been doing. Kneeling for anthems comes to mind. It's one thing to disrespect one's own flag and military. It's quite another to disrespect one's host country's flag and military if one is a visitor.
Taking a couple of days off for reflection on the state of racism in the world and its implications on the lives of people everywhere is a reasonable action for a league with a lot of national, if not racial, diversity. I am glad to see any group of people acknowledge the need to improve racial relations without doing anything which is violent, destructive, or insulting to another group of people who likely despise racism as much as they do.
Now if only we could convince racist people that their actions are stupid. Unfortunately, stupid is not fixable. All we can do is prevent it from spreading, and for that, we all need to speak up.
