Dsicrimination? Why not make it illegal to carry an ad mentioning age, or gender, or any preferences? After all, if the applicant indicated that coitus was enjoyed, it would discriminate against gays, who are not equipped and are forced to specialize in mouths and assholes.
This is the slippery slope that comes from anti-discrimination laws, a bad intiative. They should be eliminated and people provided freedom of association and the right to do business with whomsoever they wish.
What next? The cat houses in Nevada forced to provide all services to all people?
In San Francisco, the "virtue police" bust a John for dissing the "service provider" by wearing a condom.
Government intrusion in the everday lives of people is increasing. There is less and less freedom of choice, and more and more "rights" extended to some, which impose "liabilities" on others.
In some instances, this is overt, and in others, choice is limited by taxation and allocation of funds by the government, limiting the opportunity of the taxpayer to direct his own life. Rather than having a beer at Joe's Tavern with his buddies after a hard day on the trading floor, the money is taken from the taxpayer and diverted to pay for obstetric care for an illegal alien woman, who will have an anchor baby. So, taxpayer goes home, and watches TV there instead, and has a less costly brew at home annoyed with his wife and kids for interrupting his reverie with their clamor for attention.
