I think by and large the matchday supporters, whom Ferguson was addressing, have stood by him and will continue to do so.
There has been no outpouring of hostility within the stadium, I'm not sure you could say that about other clubs. Arsenal, Liverpool and Chelsea have all scummed on managers at their home stadium within the last few years. The support so far for Moyes has been a credit to the club, even though the team is in freefall. The thing is, patience does eventually wear thin, especially when worry and doubt slips into the consciousness of the masses.
From my own perspective I won't be held to ransom by Ferguson, in any moral sense. It isn't my "job" to stand by David Moyes, I'm a supporter of the club, and that isn't a job....it's a passion. That will never change.
