I doubt that the vast majority of racial blanketing cases from prossies have anything to do with the clients’ physical attractiveness as per the OP’s red herring; although I do believe there are girls who might refuse to meet guys who find very repulsive. It has nothing to do with racism in the context of superior/inferior race either. Even some black girls don't see black guys – are they racist? The reason for the blanketing is simple. Like many punters here are blanketing for example ALL Romanian girls and avoid ALL of them (because of course they are ALL bad service providers, they NEVER French kiss, etc), many prossies also adopt similar prejudice and stereotypes: e.g. Black guys are thieves, Muslims and Arabs are disrespectful and pushy, ‘Asians’ (i.e. from sub-continent India in “British” English) are haggling and/or having poor hygiene, ‘Oriental’ guys (i.e. from the ‘Far East’ in “British” English) have very small penises and the condom may slip during intercourse, Black guys are dodgy and attempt bareback, Black guys are violent, etc, etc. Stereotypes don't exist over nothing. They did start with observations on the stereotyped population but then a lot of the time they are exaggerated.
Personally I chose to judge the individual. It will be a cold day in hell when I blanket a girl simply because of being EE. Others are blanketing - their decision. As for the OP I am pretty sure he is perfectly happy when girls are blanketing anyone but himself. I find it quite hypocritical when such threads are started by such people to moan after finding themselves blackened: old guys, young guys, over 50y.o, under 25y.o, obese guys, skinny guys, big-dick guys, small-dick guys, circumcised guys, uncircumcised guys, toothless guys, bald guys, hairy guys, tall guys, short guys, muscular guys, blonde guys, ginger guys, disabled guys, guys with no AW feedback, etc, etc. Prossies are free to accept bookings from whoever they want much like punters are free to select whoever they want. Hundreds/Thousands of prossies and thousands/millions of punters. Get over it and choose someone who is happy to meet you. Enforcing things just leads to shit experiences.
