Will the mods please stop the riding dog posts. They gone way off topic from my original post.
I think the riding dog posts are an answer to your original question:
"Why be a 3.5 fighter?"
- "No reason, even a riding dog is stronger and more skillful at level one."
But I would like to see a 'positive answers only' thread (but without the falsehood about the fighter's great mechanical abilities or flavor).

About flavor: Fighter have no flavor. You can say that is a strength, because you can give them any flavor you want...
But then again, the only real flavor reason is to be a heavy armored warrior with no spellcasting ability.
And you can get the same from the Knight and the Marshal, so I will add: with no code of honor and not good at leading others.
Maybe I should add calm, too, to get rid of barbarians with the heavy armor proficiency.

Mechanically, fighters are mostly one-trick ponies or (more sad) no-trick ponies.
Being good at the one trick requires heavy optimization (badder than the one that you call cheating on a spellcaster) and using nearly all your feats for it. And it will still be no very good versus huge and bigger enemies, incorporeal and swarms.
And anything flying, if you don't specialize in archery. Just having a composite bow with not the right feats and average dexterity doesn't count.
