Don't care about it, as in, can't see anything even remotely wrong with it, never used one, know a few people who have, though that is mostly weird people at uni with stories of banging some really cheap nasty woman when they were 16 or something along those lines.
IT should be legalised, getting rid of the vast majority of the criminal element from it, which will again like legalised drugs reduce crime, reduce violence, reduce health risk, etc, etc. If it's legal, and people can make a proper living and get health checks you'll make money from tax and save money in treatment.
If your average punter can check she's registered and check she's been checked up say every two weeks for std's, you'll have less people needing treatment for std's, you'll have less spread of serious disease's like aids and it will be safer for the prostitutes and punters. You've got violent people who might go to prostitutes, beat them and it doesn't get reported because they'll get in trouble for being prostitutes, then a few of those guys esculate to rape/murder of "normal" women.
It's a large industry, its profitable, its unsafe and it generates crime, health problems and policing costs. If it were legalised it would generate tax profit, reduce crime, reduce spending on health care and reduce spending on policing costs. It would also dramatically reduce trafficing for prostitution, kids, women, being forced to work illegally. Because police would have less other "busy" work to do and because the demand for cheap unsafe hookers would basically disappear and be far easier to track(as being legal it would be safer for prostitutes and punters to tell the police when they see something dodgy).
Prude's and not wanting to seem "for it" in an age when politics is about looking good rather than doing whats good for the country. It's as simple as this, there is no down side, only upside, it would improve thousands of peoples lives in the UK, it will never happen because politicians haven't cared about what's good for this country for 30 years.
