If you limited it to IRA and their supporters, I wouldn't have had an issue. IRA has always been no friend of Jews, or conservatives, or Catholics who are in the way for that matter.
Yeah, well... by the list of factions in the example I thought it pretty clear what kind of factions I was thinking about. But of course there are perfectly normal people over there, just as there are perfectly normal people in Britain (also a hotbed of antisemitism).
