There is nothing against dwarves because we are too tough to corrupt and too intimidating to stand against!
I would actually say that the true anti-dwarves are...
Dwarves.
Now let me explain, with the other races the good/evil dichotmy is an external struggle. The elves and orcs fight physically and externally. However, with the dwarves it is a fight of their noble self vs. their base desires (best represented by their greed.) Dwarven greed is the Dwarves' greatest enemy and leads to their greatest conflicts. It is greed that drove the Dwarves to kill elves and take the necklace (with the Simral) and it was greed that caused the dwarves of Bilbo's group to turn against the elves and humans which led to the Battle of Five Armies.
So it goes to show that since Dwarves are so impressive the only respectable enemy is another Dwarf.
