I've been away so I havent had a chance to read this thread until now. Just some background on me, I'm from Galway and supported GUFC (still do from afar) until I moved to the US 15 years ago.
I love the game of soccer as all of us do here but for me it is important to support my local team. So as to the Franchise versus Euro-Style club debate, I and many more like me dont have any choice. It's either support NYRB or just follow the Man Utds or Milan or Barcelona by watching on TV. It's like the whole LOI argument. Why do more Irish people support English teams than Irish teams? Sure, I would prefer to have a local club that is not owned by a fizzy drink company. But thats all there is for me here.
It did hurt when the fizzy drink company bought the Metrostars. But what were the Metrostars anyway? A franchise. The original team back in 1996 was created by the Metromedia company and aptly named it the Metrostars. It was then sold to AEG, an entertainment company who also owns a few other MLS teams as well as the LA Kings hockey and a few more hockey teams in Europe. Red Bull unashamidly is using the team as a marketing tool. We the fans do not have much choice in the matter. We can either go along for the ride or sit at home at watch teams play 3000 miles away on TV. But to disparage the fans who go to games regulary and know the game just as much as other fans around the world do as "goonish", "no support or identity" and "don't give a sh!t" would be the same if I said the same thing about Cork City or Drogheda etc.
I must say however that Red Bull have done more in 13 months then the other owners did in the previous 10 years. They brought in the best US manager (Arena), the best US player (Reyna) among others and started builing a new stadium:

As for the small crowds. Well there are a ton of reasons that would take all day to explain. MLS suffers from a lot of the same stigma that the LOI does especially regardin the standard of play.
Add into the mix the ANTI-soccer types and the ones who ignore it because "its a foreign game" and it is always facing an uphill battle.
