I’d say it’s more that he embraces the problem, many that there are, at that club.
Celtic and their fanbase’s ‘victim mindset’ ramped up tenfold when O’Neill went there in the year 2000, along with the attitude you see nowadays of “let us behave how we want, say what we want, sing what we want and if you have a problem with any of that you are an anti-Catholic, anti-Irish right wing racist…but don’t you say or sing anything that we don’t like because that offends us”.
He emboldened them with and created a siege mentality, using Neil Lennon in particular to push the anti-Irish agenda and result of all of that is Celtic have the footballing authorities, the media and politicians scared of doing or saying anything to upset them.
Do not believe for one second that Martin O’Neill is anything other than a very dangerous, manipulative person.
