This is getting ridiculous.
There is no comparison with housing, employment etc.
Prostitution is not covered by the Race Relations Act and given the nature of the trade (a woman lets you penetrate her in return for money) it is essential, indeed vital, that a woman always has the right to choose whom she sees.
If she doesn't want to see blacks then so be it.
Most blacks are sensible enough to shrug their shoulders, move on and find a girl who will see them.
Think of the alternative: Force a woman to see a man she has no wish to see - also known as - Rape.
