@End of the Line ... there are a few impediments stopping the USOC from anointing the LA Galaxy the right to send a national team. The first is that the LA Galaxy is part of the MLS, which is a privately held, for profit entity with no charitable public purpose. This would violate the USOC's legal requirements under the Ted Stevens act that National Governing Bodies be charities. The second problem, is that the LA Galaxy team is technically an operating unit of the MLS, thus, the MLS would have to be given the right (assuming it changed its corporate purpose).
With regard to National Governing Bodies advocating for various social and charitable causes, be it black history month, breast cancer awareness, white pride, Hispanic pride, Asian pride, save the fairy shrimp, etc., I believe they should not. Its one thing to say ... all are welcome, discrimination based on melanin levels, sex, gender, etc., are not tolerated. Its an entirely different thing to say "we are going to single out this one issue, change our uniforms to recognize it, and advocate." Along with the freedom of speech, comes the freedom not to speak. The freedom to march and protest, and the freedom not to march and protest. National Teams and National Governing Bodies should establish rules that prevent violations of civil rights, but should not pick up the sign and go march.
My above opinion was reinforced as a result of an event that occurred when I was coaching my son's recreational team many years ago. It was the Fall season, he returned back to rec soccer from a bad club experience, I coached the team. The season was played in September and October. October was breast cancer awareness month. The program asked all the teams to wear pink socks. For years we went along with the whole pink socks thing ... be it pop warner or soccer, but this year was different. You see, the week of our opening game, one of my player's mother passed away from pancreatic cancer. What month is pancreatic cancer month? Hell if I knew, but what I did now is there are a whole host of cancers out there and each one has a color. If I recall, "purple" was the pancreatic color, so I informed the league that we would not be wearing pink ... we would wear purple socks.
About midway through October, it hit me that maybe instead of purple or pink or whatever color, we should just be wearing the color of socks for cancer itself ... whatever color that was. What made breast cancer so special over the other cancers. I had a player would mother died just a few weeks earlier and here are all these teams focusing on breast cancer and not the cancer that killed his mom.
The reason I don't want National Governing Bodies to take on political advocacy of issues is because for every issue there are others left out. If we are going to celebrate Gay Price and change the jersey's, do we also celebrate Heterosexual Pride?, African-American Pride, Irish-American Pride, Hispanic Pride, White Pride, etc. Its best the NGB's set policies of non-discrimination and put down the picket signs.
