i.e. shoving rabid nationalism down someone's throat - is just dickish behavior, and will ultimately affect the bottom line in a negative manner.

How is playing the USA National Anthem before NBA games dickish behavior that shoves nationalism down someone's throat? The National Anthem is nothing but a song of national pride written by Francis Scott Key, and is a long tradion of USA professional sporting events. Usually all that is ask of a player is to stand or whatever, and to be respectful. Canada does the same thing. In fact both countries play each others National Anthem as a show of respect. Other country professional leagues do the same thing. The Olympics does it for all countries.
Ultimately it could affect the bottom line of the prima donna millionaire athletes who try to use the Anthem for protests purposes. Profession sport leagues have been accomodating to any players with sincere religious beliefs. The bottom line is that the teams are under no obligation to draft these players. If any player really has a problem with showing a few minutes respect for this country or Canada's national Anthem, then maybe they should go play in another Country's professional league that is waiting to pay them millions of dollars to play a game. Oh wait, other Countries will require they show respect for their National Anthem also, but probably won't play them as much.
