The hand doesn"t start until after the blinds are posted, therefore by the time the cards are in the air, the blinds are not yours anymore. Don"t think of it as him stealing YOUR blind - he is simply stealing the pot, and doing it from the best position on the table, which if course is pretty standard stuff.
I don"t hold with any need to defend a blind with bad cards - it"s a -EV move. If this happens every time you"re in the BB, you just need to find a hand once and move over the top of his raise.... not only will you then recover some chips, but you will make him think twice about doing it again. Personally, I would not move back over the top with junk from the BB unless I had a decent read. The last thing you want is for him to call with ATC and have position on you post flop when you have rags.
