I agree with you on equal treatment for all and I am 99% sure without ever having met you that you are in no way racist. There are people though who can have their national pride used in a negative sense by far right wing groups and distinguishing a difference between different races plays into their hands.
I am completely against any sort of quota system for anyone in any branch of work because it automatically gives people a stick to beat you with if you got the job as part of a race quota, whether or not you deserved it regardless they will always think negatively about it
