Well, bal, I'm impressed.  You've compiled a pretty impressive list.  Frankly, she makes herself a target by touching on some social taboos...but most of the righteous indignation directed at her is fake.  Ever since political correctness came into vogue, people are simply sitting around waiting to be offended.

  "[North
Korea] is a major threat. I just think it
would be fun to nuke them and have it be a warning to the rest of the world."  - a joke with a hint of the the truth in it.  I operate from the perspective that ours is a country worth protecting from the threat of nuclear weapons in the hands of those who would attempt to destroy us.  Should we really sit back and let them become such a threat? 

"My only regret with Timothy McVeigh is he did not go to the New York Times Building." - Once again, a joke.  In poor taste?  Perhaps.  It's not advisable to in effect wish death on anyone...outside of the odd dictator or terrorist.

"We should invade their countries, kill their leaders and convert them to Christianity." - Now, that's funny.  It's called irony.

"I think the government should be spying on all Arabs, engaging in
torture as a televised spectator sport, dropping daisy cutters wantonly
throughout the Middle East and sending liberals to Guantanamo."  - Once again, a joke.  Geez, lighten up. 

"I’ve never seen people enjoying their husbands’ deaths so much." - I'm totally on board with her on this one.  No doubt these people suffered on 9/11 and afterwards, but they act like they suffered more than any of the other families who experienced loss.  They were pure political pawns who marinated in their newfound fame.  Politics is a contact sport...if you stick your neck out, don't expect to do so without some blowback. 

"I don't know if [former U.S. President Bill Clinton is] gay. But [former U.S. Vice President] Al Gore - total fag." - Even you thought that one was funny.

"Bill Clinton "was a very good rapist" - Fair comment. 

"I think we ought to nuke North Korea right now just to give the rest of the world a warning." - virtual repeat of first quote.

"[Canadians] better hope the United States does not roll over one night
and crush them. They are lucky we allow them to exist on the same
continent." -  Only the humor-challenged would find this one too objectionable.

"I was going to have a few comments on the other Democratic presidential candidate John Edwards,
but it turns out you have to go into rehab if you use the word
"faggot", so I — so kind of an impasse, can't really talk about Edwards." - And boy did he get a lot of unwarranted mileage out of that one!

"God gave us the earth. We have dominion over the plants, the animals,
the trees. God said, 'Earth is yours. Take it. Rape it. It's yours.'" - "Environmentalists" take themselves so seriously

Ann Coulter may not be your cup of tea, but the level of hatred and bullying she's subjected to is totally out of whack.  Is she that big a threat to your well-being?  If only we treated John Stewart or the talentless Ted Rall half as badly as we treat Ann Coulter!
