Thats what they call themselves. You dont like that?
Kinda of like some of the Muslims groups here in the US
that get so upset when their extreme brethren get them labeled.
There were Catholic priests giving money to the IRA in Boston.
And many other Catholics that detest the IRA.

It comes from centuries of hatred.
And that of course leads to trying to take political control. In these cases,
I cant separate the two. Maybe you can. You are choosing which conflicts
you wish to label rather indiscriminately.
