When you see so many ads say something like 'No black men/guys, etc'?  I just saw an ad today that says no Asian(this kinda makes my head spin a little).  Doesn't bother me and everyone has the right to refuse to see anyone.  

I think a lot of providers base their decision off of some negative experiences. Not saying that all are like that with a certain race, religion, etc. but a few not so great experiences can establish a bias. Yeah, I think it would suck but it's not anyone's choice except for the provider. I know a couple of providers who don't see Asian men just because they have quite a few Asian friends and don't want them to find out.

Is it your contention that a woman should fuck any and all comers just because she is a provider without regard to her own personal preference or comfort level? This is a much more personal business than most as well as being illegal yet you seem to think the same rules apply. At what point does a woman loose the right to choose who she has sex with?

Seriously strange statement, imo,  considering you are on a hobby board.  Were you taught it was okay to see escorts?    

Which post are you replying to? Both the OP and the first response agree that it is the providers choice. The person who stated it is due to bad experiences is likely right, although I have heard more than once these ladies are trying to avoid a pimp situation.  

My two massage providers won't see Somali dudes because of bad experiences with them; they can be grabby and cheap, supposedly. They also won't see east Indian guys because of the smell.  

I don't know what the big deal is.  
Both providers and hobbyists have their likes/dislikes, preferences, and who they're comfortable with as well as uncomfortable with.  

. . . where racism is perfectly acceptable.  We "discriminate" every day.  Some people are too short to others.  Some too heavy, some too skinny, some too tall . . . . . and some are too dark to be sexually interesting to some people.  The things that trip my trigger might trip someone else's gag reflex.

I see all races.  In my two years, there have developed patterns.  Indian men tend to be more pushy and disconnected.  Exception, I have one regular client, of Indian descent, who is polite, respectful, and fun to talk to.
Black men, I have a client who is wonderful, who I've seen several times and done doubles with.  I have had a couple others that are older than me who are very sweet.  I've had one who was pushy all to hell.

... please ... take a shower or use a baby wipe for fuck's sake.

Yes, in my circle of life,  it's perfectly normal for well to do men to see an escort and have a mistress.  When I turned 16 my dad took me to China(with my mother's knowledge) and brought me to a brothel.  When you go in, there's a bunch of ladies with numbers and you just tell them what number you want.

It's my contention that a lady who refuses to do business with a person based on his race is a racist. Particularly a white one. Extra particularly one who says 'people of x ethnicity stink' or 'i don't do black guys cuz pimp.'  

However most of my clients are Asian ( Indian included since it's the same continent) and don't use these sites.  
I believe mostly has to do with the providers don't want to get recognized by someone not so much as racism .
People can pick and choose whom they want to associate with in this industry and that's not going to change any time soon.

... stereotypes exists and persist because it's the way the human brain can quickly categorize, process and assess the environment.  Certain stereotypes will go away if they prove to be untrue over time.  Others continue on because they are generally true.

Regardless of why, no one should be required to have sex with someone; it must be their choice.  And as blatant as the ads may seem, they have the advantage that people will know up front that the provider has such a rule.  Better to find out right away than later.

If you study human migratory patterns.  Especially where "European" is concerned, "most" Europeans are the descendants of people who were driven out of Asia.

As we do, I believe.  I've heard various reasons for this including a few not mentioned here, they all involve some level of stereotyping however.
