From talking to Unionist friends in Nor'n Ireland being a member of the Orange Order is a bit embarrassing. It's also a dying organisation. Membership has plummeted in the last 20 years and the average age of those who are left is well over 50. They have no money to maintain their lodges, a very bad relationship with the Protestant Churches, the C of I in particular, and are a total shambles organisationally. It is fair to say that they are not a representation of Protestant culture in Northern Ireland.
Despite their protestations the comparisons between them and the KKK are apt. Younger Protestants in Northern Ireland are culturally aligned with England which is largely secular tolerant and liberal.
Unfortunately The Loyal Orange Institution attracts the detritus of the Protestant population, another thing they have in common with the Klan in America. That means that they still pose a threat to peace and the creation of a country/province/state/jurisdiction in Northern Ireland that is really democratic. While there may be aspect of Northern Protestant culture that are to be admired there is nothing about the culture that The Orange actually represent that is worthy of respect.
