By emotional argument I meant an argument whose strength lies in its effect on emotions, as opposed to its rational strength. Perhaps that's a weasel term. But I tried to back up my assertion that introducing bias can't remove bias.

> mechanisms seeking to remove bias of physical characteristics will still allow bias for class characteristics.

If by "bias for class characteristics" you mean "objective standards", I call that nonsense. By definition, an objective standard will cease to be objective once a subjective-based alteration is introduced.

If an objective standard happens to favor one class over another, it's not the standard's problem. The problem lies in whatever caused that class to do worse.
