Oh, well, that's simple: lots. Why? Well, remember last Thursday night? You know, when we were all watching our police force battle block-to-block in our neighborhoods with homicidal, cop-killing terrorists armed with explosives? Arkansas state senator Nate Bell thought that would be a good time to send this tweet:

I wonder how many Boston liberals spent the night cowering in their homes wishing they had an AR-15 with a hi-capacity magazine? #2A — Nate Bell (@NateBell4AR) April 19, 2013

Yup. He went there. (You can't find the remark anymore on Twitter, but you can read his apology ... and comments ... on Facebook)

So now Boston is going there, too.

.@natebell4ar You are a moron. — Matt O'Malley (@MattOMalley) April 19, 2013

. . . even the guy from MIT's Civic Media Lab found himself in a not-so-civil mood . . .

. . . our cat-mystery novelists think he's not a nice person . . .

@natebell4ar Screw you, Nate Bell. I'm a proud Boston liberal and I am glad that the professionals who my taxes support are on the case. — Clea Simon (@Clea_Simon) April 19, 2013

. . . I repeat, OUR CAT MYSTERY NOVELISTS!!!

. . . Boston-based politics blogger Charlie Pierce put it succinctly . . .

RT @tpmcnaught @natebell4ar I slept like a baby knowing I didn't have a moron like you representing me. — Joyce Linehan (@ashmont) April 19, 2013

. . . and I really don't think you wanted to get on this person's wrong side . . .

Hey, @natebell4ar, I was a sgt in the USArmy, Hawkeye, and Boston liberal. Go to hell, you ignorant douche. — ElizabethPowell (@sargep) April 19, 2013

. . . and some people thought Nate might be compensating . . .

@natebell4ar only Small Men need weapons of mass destruction to protect themselves no cowering in Boston last night Coward #bostonstrong — Don Frattaroli (@Don_2instinct) April 19, 2013

@natebell4ar Come here and say it to us you SOB. What does needing a big gun to feel like a man indicate about you? #bostonstrong — Glenn Clabo (@GClabo) April 19, 2013

@natebell4ar And if you think having an AR-15 makes you a man.You aren't one and never will be one. — Chip Crawford (@slobis) April 19, 2013

. . . oh and by the way . . .

@natebell4ar First things first: Bostonians don't cower. This isn't Arkansas. — SQLRockstar (@SQLRockstar) April 19, 2013

. . . you should have remembered what the internet said about us . . .

That makes 2 (million) of us. RT @smallbeerpress: @natebell4ar I look forward to donating to your opponent in the next election — Kelly Rogers (@interiors4fam) April 19, 2013

@natebell4ar Over here we don't need guns to grow a pair of balls. — David Haffner (@DavidHaffner) April 19, 2013

. @natebell4ar I invite you to Boston. So you can witness true toughness, compassion and humanity. Toughest city on earth. No guns required. — Ed Bogle (@MarlboroDad) April 19, 2013

That was just the beginning. It wasn't just Boston . . .

This guy's never cowered from a buffet MT @natebell4ar: wonder how many Boston liberals spent the night cowering wishing they had an AR-15? — Brandon Stosuy (@brandonstosuy) April 19, 2013

. . . or California . . .

. . . or wherever . . .

You're an absolute clown RT @natebell4ar Wonder how many Boston libs spent night cowering in homes wishing they had AR-15 w/hi-capacity mag? — Joe Haggerty (@HackswithHaggs) April 19, 2013

. . . or Chris Bosch (not that Chris Bosh) . . .

Dear @natebell4ar how can you say things like that? As an Arkansan and an American I'm appalled. Please think before you tweet. — Chris Bosch (@chrisleebosch) April 19, 2013

. . . but we'll let a former Bostonian have the last word, since he put it so poetically . . .
