Yeah, let us sink to the levels of Liverpool patriotism - that would be something. Gerrard wanted to win the PL - Rooney had no such arguments to be made concerning United as under Ferguson, we had won everything. He also did this twice, so it's different.
As for Giggs - I lost a lot of respect for him, and I think many did. Cheating is one thing, but with your brother's wife... Giggs never, however, spoke ill of Manchester United. (that I can think of)
Last sentence: you are right, he was all those things, but he is not anymore. Nobody is arguing that he wasn't a great player, but people are arguing that his time has been up for quite some time.
