"Mr. Bush" is not an insult. Suggest you save your rage for something a bit more important.
I agree it's not an in-your-face insult; I just assume from her language it's a lack of respect innate in the MSM. And don't worry, I have plenty of rage to go around!
President Bush, or Mr. President are appropriate. The entire MSM uses Mr. Bush, but always said President Clinton. While energies might be better spent on more significant issues, I have to agree that this pi$$e$ me off, too.
