Regarding the explosion: No, shochwaves and debris are not dumb and if you think so, you havn't really thought the whole matter through to the end for the following reasons:

Yes, fire is the initial spark (no pun intended) of almost all explosions, but Jackal could just start the explosion in front of Natsu, a little distance away, rather than directly on his body.

Thus Natsu couldn't eat the fire, since it's out of reach and he's hit by the shockwave and whatever it carries with it. Or he could cause an explosion in the ground beneath Natsu's feet or inside something in Natsu's surrounding, which would result in something like a make-shift frag-grenade.

So yes, there should be ways to used even fire-based explosions that still don't allow Natsu to just negate them. Too bad Jackal (or Mashima) only thought to use the explosions in the most straight-forward way so far.

Putting that aside, the moment of the actual explosion, where it is solely fire is less than a second. By the moment you saw and heard the explosions, the shockwave has already been unleashed, so by the time Natsu notices the explosion, it should already too late to prevent it from happening by eating the fire.

So no, Natsu eating the enitre FULL force of the explosion like he did in the manga does NOT make sense from a physics point of view. At that point that he did ate the flames, the shockwave should already have caused damage to him.

Saying that Jackal should beat Natsu BECAUSE Jackals attacks are fire based really does make no sense though, still as FTGM pointed out already, it'd be better to use less offensive ways to dismiss a theory or opinion than outright calling it dumb.

And if you look around a bit, you'll find plenty of positive blogs particularly about people's favourite characters (or certain body parts of the females, make of that whatever you like), only that nobody has made one in the last few month.
