If some one spoke to a member of your family in the way he did I persume you would find it out of order.
Just because the ladys' profession is escorting does not give him or anyone the right to speak that way to her.
While I like things to be debated strongly some tend to forget simple manners. I was brought up to respect women and just because I am not speaking to her in person but through this medium does not change my approach!
That is just my opinion!
