(Seattle, WA)  --  Sounds supporters are unifying against the league's ban on political signs.  The majority of the Brougham End supporters group walked out at the beginning of the second half in an act of unity with Emerald City Supporters.  The Emerald City leader was removed at halftime for displaying an Iron Front flag during the first half.  The league has determined the anti-fascism flag to be political display, which the MLS banned prior to the season.  Groups from multiple teams will meet with the league in Las Vegas Thursday to discuss the ban.
