As others have said over and over at this point that compromise should be the goal. What you are seeming to have trouble grasping is this if the compromise is something the DM can't or does not want to do, like say adding gunpowder to a setting, then yes the player not the DM is the one who has to compromise. And I get you don't think that is fair but I disagree.

Just to be clear, this is what I'm saying:
In a case where the DM cannot make a case for disallowing something beyond a simple, "Well, I don't like it" then I do think that the DM should allow it. That's certainly how I DM. Obviously others see it differently.

OTOH, there may be all sorts of perfectly reasonable reasons for disallowing something - it breaks the game badly, it doesn't fit with the game, it violates genre, it would cause me to have to do a bunch of work (I am, in fact, very lazy

). Any of these reasons would be perfectly acceptable. Let me illustrate:
1. Player comes to a Forgotten Realms game with his Jedi. Player is wrong. Player needs to get with the program.
2. Player comes to a Dark Sun game with a priest of a water god and can create food and water virtually at will. Player is wrong. Player needs to get with the program.
3. Player comes to a fairly stock fantasy setting with an off the menu race that fits with genre and is balanced in the game. Unless there's a campaign specific reason not to allow this, the DM should allow it. It's simply far too easy to adjust a setting to allow for this.
4. Player comes to the game with a new source book with a new class he wants to try out. The class is balanced and isn't a mechanical problem and fits with genre. DM needs to relax and trust the player to bring something interesting to the game.
That's how it works
for me This is how I believe that the DM should act. Now, again, obviously, other DM's will disagree. I think they do so to the detriment of the game and I'm very reticent about playing in any group where the DM is that inflexible. And, there is room for considerable nuance with numbers 3 and 4. You'll notice that I agreed with [MENTION=16528]Pirate[/MENTION] Cat's compromise examples for the different races. I believe that a reasonable player probably wouldn't have a major issue with the proposed compromises.
But, at the end of the day, compromise is a two way street. It's not that the DM compromises when he feels like it. The DM should compromise unless there are better reasons than, "Well, I just don't like your character".
