"I do not understand why you say they parade to "prove their superiority."
You seem to have led a very sheltered life.
A couple of verses of "We are the sons of Billy and to Hell with Popery" should sort out this for you.
A few years ago a friend on a visit to Belfast decided to balance his collection of Irish music with some Orange songs, so he asked around and was directed to places wheere he could buy some 'under-the-counter' home made albums - I don't think he quite got over the experience - a torrent of sectarian, racist, right-wing hatred - the pride of place of his collection is held by 'The Pope's a Darkie'.
"Loyalist do not have the monopoly on hate and intolerance."
No they don't, but it is their marches and their insistence that they should march in places that will cause the most disruption and insult that instigates and keeps that hatred alive and simmering.
