There's something that differentiates the two and makes one more acceptable than the other. I'm not sure exactly.... but it could be a number of the following:


Porn stars:
Registered
Must wear condoms
Vigorous STD Testing
"Basement" Entertainment
Apparently they act sometimes too
Celebrity Status
Inaccesible (that is you can't touch them)


Prostitutes:
Are extremely Accessible
Placed in constant risk & danger of infection/physical damage
STD testing is not available upon request
They pleasure you directly
Illegal solicitation
Not registered



I think mainly the concern is that pornstars are registered and ndergo constant STD checkups to ensure they're not spreading a contageous and harmful disease. It's deffinately illegal to knowingly transmit an STD .... so I think the government has taken protective action to attempt to ensure that citizens are not being placed at risk. Since pornography can't transmit a disease to you directly I think it is less shunned and valued differently as opposed to an anonymous prostitute on the street who is selling herself for God knows what and may not really care if she/he passes on life threatening STD.
