I don't suppose this "race" is asian by any chance is it? If so there are plenty of threads about asian clients on here already. I know it's difficult not to tar everyone with the same brush when you've had bad experiences but be very careful. You're on shaky ground. I?m aware of what happened to you a few days ago (and you have my full sympathies) and I suspect, understandably, this has a lot to with this post. If you had experienced the assault by a white guy, or had a few bad experiences in the past with white men, would you now be here asking how to screen out all men from the Caucasian race? I think your problem is you?ve had the misfortune to encounter wankers, who by the sound of things, would still be wankers even if they were to be white, blue, yellow or pink.
