"But if any Plastic Paddies could join me in rousing renditions of wearing of the green, get green ring tones on your phone, wear green, especially on Sat. 4 p.m. Iranian time whenever that is...set facebook background to green,"

Eeek! That's just horrid frankly. I'd suggest, if you 'want to make a difference' then avoid all the above, and instead go to see a Samuel Beckett play, read some Seaumus Heaney, listen to some Sean Nos, or check out the vast array of ancient Irish megaliths that this small island is home to. So very much you can do to discover and celebrate your Irish heritage which isn't trivialising to it or its people. And no shamrocks in my stout either ta... ;-)
