So much as who?

So much as Protestants & Catholics hate each other in Northern Ireland? So much as Greeks & Turks hate each other in Cyprus? So much as Sunnis & Shiites hate each other in Iraq? So much as Jews & Arabs, Hutus & Tutsis, oh, the hell with it. Despite much trying, no-one as yet has managed to convert the US to an ethnic pest zone. I won't go so far as to say it can't happen here, but I can think of several reasons to say it isn't likely.

Stopping short of smugness, we may very reasonably count our blessings.
