OK, but probably every white KG player knows that he shouldn't play fxe5 before Nf3, except maybe one who just tries this opening once because it comes to his mind ... my experience is that hoping for one specific blunder by my opponent is almost never rewarded :)
A very brutal response to kings gambit

I think the spirit of any gambit is to not be afraid to go down a pawn. I don't know any king's gambit lines but I'm guessing after 2...Nc6 white usually plays something like 3.Nf3
Especially considering 3.fxe5 is completely unplayable due to the queen check that you showed.
After the queen check the moves you give for white are so horrible I'm wondering if I'm watching a help-mate problem :p

Seriously though declining a kings gambit makes way more sense than accepting it for black. At least 2 out of 3 times a black player in the kings gambit is gonna accept the gambit. So the white player is going to prepare twice as much for it to be accepted than declined, but in declining it you have all sorts of options instead of 2... exf4
You could play... d5, Bc5, Nc6, Nf6, Qh4+, d6 maybe even try something like c6 or f5
Basically black has a ton of ways to respond to Kings Gambit, and most white Kings Gambit players are gonna put way more effort into studying the accepted lines, and playing other moves will probably get them away from what they studied for.
brural - somehow i imagine angry farmers with pitchforks ...
was a typo of brutal, I'm a big fat american and my finger is to fat to punch the keys and I ate the lickerish I was using to punch the keys with :(

Sad but probably TRUE!
Most Americans are overweight

You're relying on 3.fxe5 - no kings gambiteer in his right mind would do that.
The whole point of gambit play is to gain tempo. In principle, the pawn has allready been sacrificed; no point in trying to hold on to it on the very next move.
There's another reaction to 3.fxe5 Qh4+ which is of course the amusing 4.g3 - the same Z-maneuvre applies and wins the kings rook. No thank you; I'd rather go for a win ;)

King gambit is full of landmines for both players. If you know to play it well for white, you will beat anybody rated under 2000 very easily. I have played this game yesterday on one local open rapid chess tournament against opponent rated 1900 FIDE (I am 1000, unrated yet).
I made a blunder later in the game, but won anyway easily.
And the line 5. Ne5 is one of more sound lines. Just remember, that anybody who is playing KG against you is underestimating your preparation and hoping you to make a blunder early in the game.
My point is, there is no reason to decline it, if you want to win easily. I tryed to play KG declined, but didn't work well and pressure from white was tremendous anyway.

I'm sorry, but nobody is going to play King's Gambit like that. Everyone who plays KG knows to play Nf3 after f4.
If you ever get into this line you should be able to win. This is why I like to decline kings gambit sometimes
