Of course. Where, then, are the passionate Coyotes fans trying to keep their team? On the Internet? This is part of the reason people make the Winnipeg comparison, with the massive public rallies and kids donating money from their piggy banks, etc. etc.
Nothing even remotely similar has happened in Phoenix. While I agree a small rally of, say, a few hundred fans in Phoenix probably would get unfavourably compared to Winnipeg's tens of thousands, at least it would be a sign of life. I think any sign that the Coyotes fans are fighting to keep their team would calm down a lot of the anti-Phoenix talk both on forums like this one and in the media, but so far, there has been nothing. People aren't even showing up to the games.
While I'm sure there are many others like you who are passionate about the team, those of us on the outside aren't seeing any evidence that they exist, which leads us to believe the team is unappreciated in its current location and should be moved.
It's pretty straightforward: the Phoenix fans don't show any support in public, so everyone else assumes there are no Phoenix fans, and calls for the team to be moved.
