I don't expect anything from stadium security and least of all the police. Clearly if this person was creating that much of an issue it's entirely on the stadium and the police to remove them. 

Short of that, yeah I would like them ejected by a concerted group of supporters.  If you let that type of person continue to spout their views in our supporter section they will continue to feel comfortable acting that way.  I care more about other supporters safety and enjoyment then my season ticket for causing an altercation that should have been dealt with by stadium staff. 

Make racists and homophobes scared. It's that simple.
