Ah, so we're back to arguing most men go now, are we?!
We'll it's only last year that I left the UK after 13 years living there. I must have been the start of a mass exodus, if your stance that in any week c. 120,000 men go, and that's most men. What's the population of the UK again? Over 60 million, isn't it? Come on. Even taking the women and the under-agers out - in whose world is 120,000 - your entirely guesstimated figure - most men?
Even the men on this thread who claim to go, say that they hardly ever go any more (distancing themselves from it all - why would they do that?), but when they did, they really only went on 'special occasions'. I'd say then, that it's a significantly smaller group of hardcore regulars making up the basis of the audience.
And as I said before - a point that Jo took delight in scoffing, but that's obviously pertinent - if most men truly did frequent these places, they'd be on par in prevalence with bars, pub and clubs, etc. And they're clearly not.
In other words, most men do not go to SEVs. Most men do not need them. Most men can function quite happily without them. Most men's crime rates go neither up nor down with the absence of SEVs in their lives - because it's irrelevant to them.
As an aside, I name-change on a regular basis on this forum, but the one consistency is that I will always argue the toss and stick up for good, kind, decent men. I'm lucky to have only such men in my life and am raising my DS to be another one. I will always argue for every woman's right to have such a man in her life, and not to put up with anything less.
There's clearly plenty of these men out there who don't need SEVs in their lives - and as long as there are, then here I will be arguing against such places' existence (again: not by banning; but by challenging mindsets so that the demand dwindles of its own free accord). Clearly enough men don't need these places. They're not an essential requirement to function as a man.
Yes it is conjecture, so you think if the LDCs closed the demand would stop? Well personally I doubt it. But that is just my opinion.
Hang on, so it's OK for you to post based on 'conjecture' and 'opinion' but you'd like the rest of us to stick to hard facts? OK... Makes sense. 
I have to get ready for work now. Will drop by later this evening.
