Human Ranking in British society

I don't know how others feel about this, but I find it seriously disturbing.
The "equalities monitoring form" when applying for a job in the UK, ask you to LABEL yourself under the following categories:

If this is socially ACCEPTABLE it must mean there is something VERY WRONG with the mindset of our society. First off, does it even matter what ethnic origin a person has? What counts is that the person is suitable for the job, nothing else!
What disgusts me the most is the classification and RANKING they made depending on the person's race....check it out!
So you are an A if you are WHITE, a B if you are a WHITE "contaminated" with another race, a C if you are Indian/Pakistani/Bangladeshi, D if you are  BLACK and any other extra ethnic group not even worth categorizing is E !!!
And even if you belong to the so called A group ( that meaning that you are a " fine specimen " of THE ALPHA RACE), you are still ranked according to your grade of PURITY.... BRITISH of course is the top, then the Irish which is like a bad version of the original BRITISH and then all the other "whities", which of course are inferior to the two above but still belong to the White Alpha RACE, therefore deserving the A label.
IF THIS IS NOT RACISM, I DON'T KNOW WHAT TO CALL IT!
