Homeschool and socialization

I am often beaten up with this. I don't care. Things like this often happen to me but today took the cake.
At the store today some one asked what school Emma went to (as it was during the day and she was not at school). I replied,"we homeschool." The look of shock and then immediate condemnation followed.
And this was their quote. " Oh My GOSH(will not write what they said) have you ever seen that episode of wife swap where the people homeschool? Their daughter went to college and to a party and she did not know what to do or how to act, she did not know she was supposed to drink!"
I rest my case.
Well almost, I can't leave that alone. If what you are telling me is that if I don't send my kid to school she will not learn how to drink in college your argument sucks. We homeschool remember! We can teach her to drink at home. Not really but come on! Is that the pride of any parent? It is the hope of every parent that their kid will go to college and study and not drink! We don't live in la la land. I realize the temptation will be there and by homeschooling them they will not be protected from such realities. But don't try to tell me I am screwing up my kid because she is not learning how to socially drink alcohol or smoke pot or curse. Your theory was debunked the minute you used a reality tv show (that blows by the way) to tell my kid may never learn how to act like an ass!
