With reference to the 'push' in the wall, Young barely nudges Cabaye. Cabaye never reacts nor complains, the ref doesn't deem it a foul, and besides it had no bearing on the goal as Rooney's strike was directed a good 8 feet from where Cabaye was even standing.

Had no bearing whatsoever on the goal.
Yes the goal rebounded and was lucky but did it strike Hernández's hand? From one angle it is inconclusive but from behind the goal you can see Taylor kick the ball at Hernández who is trying to get his hand away but the ball strikes his midriff and not his hand. Also watch the reaction of the Newcastle players. Only 2 raised their hands in a half hearted appeal. Correct decision to allow goal to stand.
With reference to the penalty, crazy stupid decision. Yes the lad never divided but lets not deflect. The stupidity of what happened at OT has nothing to do with Ben Arfa but everything to do with the officials. Rio played the ball, good tackle and not a penalty. End of.
Rooney should have been sent off!!!

For what! Trying to kick the ball away Coloccini

The ball got trapped and both players where trying to get at it. Rooney managed to kick the trapped ball once but Coloccini then managed to nick it away and Wayne kicked at nothing!!! No further contact with the ball nor the NUFC defender. Did any of the NUFC players around the incident who had a view react? No. Only Ben Arfa who ran god knows how many yards only to enflame a situation that is well not out of control! What a prat.
Finally nice to see that you have neglected to mention the other pathetic decision towards the end of the match, to rule (incorrectly) offside Hernández's goal. Hernández is level with Ryan Taylor when Giggs plays the ball. Hmmmmmmmmm. Attacking player level with defender. Onside. And to think, no one gets decisions at OT expect Utd. Yeah right.
