Oh, well, people just don't get it. If you want to be a prostitute, you can choose, believe it or not, to be abused by your employer or your customers! Legalizing it would simply mean better protection for the *** workers, from human trafficking, abuse, drug addiction, sexually-transmitted diseases, and others; similar to the benefits regular employees of any public or private institution would receive. Prostitutes can organize unions and all to better protect themselves, but that is another story.
Keeping it illegal is nothing more than a religious and moral issue, since the almighty Catholic Church and other Bible-thumpers (and others who wish to impose their moral standards over others), have unnecessary influence over Philippine politics.
