Losing one's head

In 2003, the BBC described Alan Pardew as 'a dangerous and distant animal'.  More than a decade on,  the Newcastle Utd manager has fully justified that tag with his senseless headbutt of a Hull City player.  Now, it wasn't a Glasgow Kiss of brutal proportions but the jerk of the head conveyed intent and it is disingenuous of Pardew to claim that he was trying to move 'the victim' away with his head.  It is inexcusable and the Football Association should punish him heavily.  I would say though that it shouldn't be more than five games stadium ban otherwise they risk making this rash rush of blood to the head worse than Nicolas Anelka's long-planned anti-Semitic gesture (the quenelle - the reverse Nazi salute popularised by an anti-Semitic 'comedian') - Anelka should have been banned for longer and now the FA is in a bind by such leniency.
As is pointed out ad infinitum, Pardew has 'previous', instantly associating him with criminality as well as recidivism.  This witch hunt to drive him out of football is to what I object to the commentariat.  Robbie Savage has lost all perspective and said it is worse than Luis Suarez's biting of  Branislav Ivanovic because Pardew is a manager.  Pardew was pushed out of the way by a former Sunderland player and this brought up his anger - a headbutt is a standard expression of violence by many.  Biting someone (and in Suarez's case this is more than once) is a particular kind of vicious derangement.  Let us not forget flavour of the month Jose Mourinho who extended his Chelsea team's lead at the top of the Premier League today but when he was manager of Real Madrid he tried to gouge out the eye of then Barcelona assistant coach Tito Villanova in a pre-meditated attack after a Copa del Rey match.  For me, that is far worse than Pardew losing his mind and temper.  And Mourinho has previous, impugning incorrectly the NHS in the Reading area after his goalkeeper had a head injury - no apology ever came from Mourinho.  He also contributed to the early retirement of referee Anders Frisk after questioning his integrity and prompting death threats to Frisk; again, no apology.  There are other incidents as well.  Yet the media lap him up.  Another line of attack is that any touch line ban is meaningless as Newcastle are in no-man's land of safe from relegation and unable to challenge for a European place.  But Roy Keane got away with far worse when he was banned for several months for ending the career of Alf Inge Haaland and foolishly admitting he intended to 'do' the unfortunate Manchester City player after a perceived slight.  Upon being banned, he embarked upon an operation that he had needed for a while - thus the ban coincided with Keane's recuperation and convalescence and the FA couldn't do a thing.  Yet he is now a valued member of ITV's football punditry.
If Pardew was sacked for gross misconduct, I wouldn't shed any tears but would fear who would be brought in to fill Pardew's office.  Once talked about as a future England manager, that has gone forever.  All I ask is for some perspective from the hysterical and hypocritical media.
