Linden/ Policy: those are really good, thoughful posts.
Linden: you're absolutely right. I've been to quite a few lap-dance clubs on stag weekend and never generally think about the implications and I don't think most guys on a stag-weekend give it much thought either. Having seen it discussed on MN quite often, I think I'd give it more thought now.
Policy: You're right about the mixed messages which is one of the reasons why I was never really keen on these places even when single - I'd rather have a girl actually fancy me than pretend to fancy me. That being said, whilst conceptually it's dangerous to send out pissed up, turned on blokes into the night in terms of the research, I'd be honestly interested to see the research linking lap-dancing clubs with increased violence against women. The original article (in the OP) was just woefully written. I also looked through the Lilith Project Report (and the extended report in 2007) which you linked but the crime statistics section was brief, confusing and just really short in terms of analysis. The 2007 report just reiterated the result of the 2003 Camden analysis. It seemed that their overall conclusion in both reports was not that opening of lap-dancing clubs increased crime against women but that it caused (as they term it) 'environmental health' problems, e.g. minicab touting, large groups of drunk men etc. Personally, if it was shown that there was a link then that is a very good reason in itself to ban lap-dancing clubs.
If, on the other hand, there isn't a link then why would we be banning it? If the customer (the guy) and the woman both freely choose to participate in the situation, what is the reason for banning it? Looking through the Lilith reports (which let's face it, aren't exactly non-partisan) I can't see anything which says women are being forced into the job - in the article in the original OP, the woman, whilst saying it's a disgusting and degrading job, chooses to do it and chooses to leave it. Now clearly, even in the absence of any statistics I imagine there will be some women who are forced into it, but, as in any industry, the way it's dealt with is through legislation and enforcement rather than putting a block on the entire industry.
