It royally pisses me off, too. It seems like an obvious thing to do, to me! I mean, really, young adults who want to be productive members of society and who entered the country under age 16, when they had little to no choice in the matter, should be allowed to become legal. Many of them barely spent any time in their "home" country and for all intents and purposes are American. It seriously seems like a no brainer to support this. But apparently not. Arg.
At least there's DADT, which is long, LONG overdue.
