I just think it makes much more sense that different races have different physical and mental strengths. and if that's not ok, why is it ok that they have other abilities and feats that are based on their physiology and mentality.
In tabletop, it's easy to to try and convince your DM that your halfling fell in the into the magic potion when he was a boy and now has supernatural strength.
But i feel that you need some hard set rules, to guide players. The more these rules gets removed the blurrier the game gets. In a couple of editions maybe we even have a totally classless/raceless system. where anybody can do anything.
