Is defending the right of Northern Irish protestants to be Northern Irish Protestants racist? Nobody contests the identity of English working class people to be English working class people. Whatever you think of the Orange Lodge as an institution, being "Orange" is part of that Protestant identity, a legitimate Irish identity. The Irish tricolour was designed to reflect that bicultural Irish identity
"The white in the centre signifies a lasting truce between Orange and Green and I trust that beneath its folds the hands of Irish Protestants and Irish Catholics may be clasped in generous and heroic brotherhood."

Still being "Green" is seen as being more authentically Irish than being "Orange" after 400 years it is still acceptable to dismiss Protestants as "white settlers". Rebel songs are wonderful, the Sash is still beyond the Pale.
