You couldn't rip on a guy at his own funeral with the national media and his whole family there. It would look awful. I mean, really, really bad.
He was a neocon hawk to end all hawks, yes.
He did very little good, foreign policy-wise and was a potential harbinger of World War III. His running mate in 2008 was the supreme Mongoloid Sarah Palin, who is barely qualified to be a Wal-Mart greeter, much less the governor of an entire state.
McCain was not a good politician, and if Lindsey Graham -- the ass-kisser for the nєω ωσrℓ∂ σr∂єr who is far worse on foreign policy than him, whose only desirable quality is that he will eventually die, cries while canonizing you in the Senate, you're a horrible politician.
Good riddance, for the most part, but not at his own funeral. Wait until after he is interred. If someone in the establishment media wants to mete out some harsh criticism and potentially risk their jobs à la MSNBC and the Iraq War, be my guest. But probably not at his own funeral.
