I think Labour's quota system was based on gender, not race.
If there was a quota system for ethnic diversity, would that be inherently racist?
If there was a full quota for your ethnicity, you would be refused because of your ethnicity.
Would that be racist?
And if someone was promoted on such a quota system who would not otherwise have been, would that be racist?
And would suggesting that might have happened be racist?
Please stay on topic, folks. There are trolls about and this could descend into a racist battle ground. Just letting you know that this will not happen!
