Hate playing against the najdorf or modern dragon?

 Nope(unless the mainline is different than I thought it was)...It is a structure which can come about from many different opening systems.

I'm not sure if you can force a maroczy with 5. Bd3 (for the same reason why 5. f3 also can't force it). True, you managed to leave the c-pawn unblocked, but you also need more control of d5. Black can respond like this:

 6.  n-f3 and 7c4 reaches a good variation of the kalashnikov for white according to soltis

I'm not sure how that would transpose to the Kalashnikov (maybe you could post the line leading to it).

Even after 6. Nf3 black can still push d5 and avoid the maroczy bind with a playable position.

This looks playable for black, and is very forcing. White has very little opportunity to deviate.

Another possible line: 6. Nf3 d5 7. exd5 e4 8. Qe2 Qe7 9. d6 exd3 10. dxe7 dxe2 11. exf8(Q)+ Rxf8 12. Kxe2 Nc6 13. Nc3 Bf5

 Its playable for black if he likes being a pawn down.....8. b-e3,qxd5 9. n-c3

Can you play it?  I certainly wouldn't want to be playing the black side of that against a player that is just as good as I am.  While you MAY be able to get a draw out of this with very good play(that is the case in most positions out of a good opening) you are in fact down a pawn and your best prospects are a draw(why not just play a petroffs if that is what you were looking for?)

Not entirely on-topic, but I feel the fried liver attack is a good example of this. 

But anyway. As was said, a low win-rate for white is probably due to people played Bd3 because they don't actually know any lines! It'd probably do a lot better if people where playing it intentionally. (i.e. with some lines planned)

bd3 does nothing good <-<

That pawn comes with a price -- white will have trouble developing the b1 knight: 8. Be3 Na6 9. a3 Nc7 10. 0-0 Nxd5 11. Nbd2 Nxf2

The burden is upon white to solve this problem. White will need to spend some tempi to get that knight out (not to mention the a1 rook), and meanwhile black tries to stir up more trouble. In master-level CC games, white might wiggle out of trouble with the extra pawn, but at club-level OTB games, I think black has good play. Besides, as white you want to create threats instead of responding to them, but now white's game plan has basically boiled down to this: grab the pawn, avoid the tactical traps, and get to the endgame.

 you do nothing good....Ba dum ching

Seriously,  I would think you would recognize that b-d3 does in fact protect the e pawn.  Therefore it does in fact do something good.   

 hmm, interesting.  I hadn't even looked at n-a6.  That might be a pretty drawish proposition actually. 

I wouldn't call a lost pawn a lost game.

Especially my games which almost never reaches end games.

I sometimes do this.

If you hate playing against those, just play the 2.c3 Sicilian, aka the Alapin, aka the Caro-Kann Sicilian!
