Maybe I'm personalizing it too much, but I think the situation is now qualitatively different.
I know that I never felt such loathing and contempt for a president as I do for Obama. I didn't like many of Bill Clinton's policies, and I voted against him, but I still respected him as commander in chief. I could trust him to make an apolitical, wholesome speach to children.
I can't say the same for Obama. I simply do not trust him for a second. Everything he does seems to be calculated to advance his radical agenda, which I loath and which I believe might very well destroy the country I love.
My hunch is the same thing is true about GW Bush and people to the left of center. The loathing and contempt they had for him was unprecedented.
But what you're directing towards Obama we all saw directed towards Bush. And we'll see directed to the next Republican president and the next Democrat president, whoever he or she may be. It's gone past partisanship and is now visceral. I don't think it bodes well for us as a nation when a large segment of the population at any one point has such a burning hatred towards the president.
