Hilarious! The "East Coast Represent!" which may actually mean "East Coast Representative!" (but what's a minor thing like coherence in writing?) responds by using that staple of the schoolyard, name calling.
What is most revealing is that name calling by a supposed adult is perfectly fine behavoir here while the use of "pissy" is a bannable offence.
Some might even find the use of "retard", in an attempt to insult, to be on par with a crack like "semi-literate gook". Neither should be used by adults in polite and public discourse.
You know what? It's okay to be a little self-righteous if you're actually right.
