On Rudy Giuliani Claiming that President Obama Doesn't Love His Country

I have a lot of problems with Obama but the fact that dude isn't a significant enough spokesperson for the American Imperium clearly isn't one of them. Yes, Mr. Giuliani is entitled to his opinion but it takes more than an opinion when you start to cast dispersions on another person's motivation (and, no, policy differences do not count), in my mind. I mean, I could say that Mr. Giuliani is doing this just to say relevant (impugning his motivation, in other words) and who in the hell could say that that's right or wrong?...Or fair?
