Do you think it would be illegal for an aids infected person to sell saliva
 

Do you think it is legal if someone has aids and sells his saliva online? In the US, that is. Wait a minute, is aids even transferred via saliva to begin with? If not, then blood or semen or anal juice or whatever.

why would they want to sell it?

wtf? planning to sell it as poison?

it's not right, unless it's for scientific research.

uh, yea that should be fucking illegal

Well of course the stated reason would be for 'Educational purposes only'. Who knows what the buyer would do with the stuff once they get it. The question is, is it legal?

yes ......
