Irish Nazism?? Irish Islamic Fascism?? Doesn't ring any bells at all. There are some muslims in Ireland today who I'm sure would join the Jihad, but the Irish Govt. is keeping an eye on them I'm sure and Irish society is not as muslim as the UK or Germany or Holland. There were Fascist elements in ireland in the 30's, but there were in Britain, the United States and every other western country too. In Ireland, unlike in Germany and Italy, they never gained power.
Then you've got a lot of reading to do, beginning with my initial post--SUPPORT for it. I never used the two terms you use, though there indeed was a Nazi movement in Ireland. When you've learned something maybe you'll be worth discussing the issue with, but I've no time for deniers and whitewashers.
If you mean the Blueshirts - they weren't fascist.
