First, Sweetness...Bravo.
It's good that she's able to support, and provide for, them. But, has she sent the message that they must disrespect themselves, and sell their bodies, in order to succeed in live?
How is she disrespecting herself? Would it be better if she sat back and collected government funds instead of going out and finding work? Sometimes in life we find ourselves in situations that are less than ideal and it's bad enough that we have to fend for ourselves, but when you have children I imagine you would do WHATEVER it takes to provide them with the necessities of life.
You may think she disrespected herself for taking her clothes off, but guess what, we are born naked, but that is besides the point. I have to ask what do you think of what Bernie Madoff did when he was fully clothed? Compared to that, there is honor in being a stripper.
