As President Obama said on Sunday, “We have to decide if that’s the kind of country we want to be. And to actively do nothing is a decision, as well.” (My emphasis.)
He's right: we've decided.
I used to believe in American Exceptionalism. Provide universal health care like every other developed nation? Sure; why not?
Provide safety from gun violence like every other developed nation? Um, if we can't pass sensible gun regulation after 20 children were slain in Newtown, Connecticut four years ago, then it can't be done.
