Lap dancing & watching someone grab their crotch are a couple of things I have no desire to take my family to see
I can understand that but I an not sure I would either of them as indecent, not to my taste as family entertainment, possibly.
I am not being funny here but it is strange world and there is the possibility that you may one day find a member of your own family doing these things.
There are a lot worse things that they could be involved in surely?
