Terrorism & bagels

Today in passing I said to an American: "In Britain we have more flavours of terrorism than we do of bagel."

Then I wondered if it were true.

British Bagel flavours I've encountered: 
Cinnamon & raisin
Plain
Onion

Total: 3

British Terrorism flavours (not personally encountered, drawn from news).
IRA
Unionist
(I think you can count both, even if unionism isn't really a terrorism on the mainland?)
Islamic
animal rights extremists (I don't think they have actually killed anyone, but the most extreme actions *probably* count, as being designed to induce terror?)
Meibion Glyndwr (??? still current?  Are Meibion Glyndwr still burning the odd holiday cottage?  They definitely don't kill people though, not sure they count)

Total: 5, sort of.

I don't think Mebyon Kernow count, not even the ones that deface English Heritage signs.  That's just graffiti.
