If we're talking about adults, they can be given the responsibility to make the right call to fit their moral or cultural code. I obviously don't condone any activities in these bars that are illegal, but I don't think that banning all dance bars is the answer.
If you don't like them, don't go ! Don't impose your morals or opinion of national culture on others. There's obviously a market for this, and as long as it's legal, there should be no problem. Should we try and ban all bars as well, or is drinking not sufficiently corrupting our country's youth? I'm not sure why politicians feel like they're the moral police of their country.... they're not morally corrupt, just plain old corrupt !
