My personal beef is with race optimisers. People who select a character race based solely on it's benefit to a specific class that they want to play. Without regard to really anything else. They may role play it to the hilt and it still may be fun but at first blush any race that isn't an iconic PC race (or race class combo) it grates on my nerves.
So dwarf wizards are right out? I have no experience in 4e, but in 3e, with a few exceptions, optimizers find their races in the PHB. Your complaint seems less about optimizers then people who play unusual races or race class combos.
