I blame Bush for this

He let them kill Captain America!

For real. You can kill Superman. You can cripple Batman. You can tell us that the Spider-Man we've been reading for the past 25 years was actually a clone created by the Jackal and thought to be dead while the real Spider-Man has actually been wandering the country as a vagrant but is actually not the real Spider-Man but rather a pawn in an elaborate scheme concocted by Norman Osborn who we all thought died after he killed Gwen Stacy but was actually alive and pulling strings from Europe the whole time.

But killing Captain America? How low can you go? The whole point of Captain America is that he can't be killed. I haven't read comics for several years, but there are things that always remain constant. And the unkillability of Cap is one of them. Need I remind you that this guy fought in World War II? We're supposed to believe that he can be killed? Captain America has gone toe to toe with Thanos! He's beaten the Absorbing Man, Fin Fang Foom, the entire Kree race, a Cosmic-Cube-empowered Red Skull...I could go on. For him to die (and from bullet wounds, to boot) is completely, absolutely, positively beyond a reasonable suspension of disbelief.

I know, I know. As my friend just said to me, death is immaterial in comic books. Captain America is the glue that keeps the Marvel Universe together. He'll be back. (After all, he has to live to protect Mar'vell in the Earth X future.) But it's the principle of the thing. Is nothing sacred? If Captain America can die, any of us can. It's a crazy world out there. We used to have a security blanket, and now he's gone. Sad.
