Political correctness aside:what are your thoughts on "Stay at home Dads"?

I know that it is not politically correct but every time I meet a stay at home dad and he tells me of how he stays home while his wife works,I aways think of inappropriate things about them,which I keep to myself by the way.
Even when I heard that Garth Brooks gave up show Biz to be a stay at home dad,I thought what a woos !
