Akuperma, I agree with everything you wrote here. I’ve been saying the same thing for a while. Furthermore, for a realistic view of how a slave was treated look in the Gemara and Medrashim. The Gemara says that not necessarily would a slave desire to be freed, since his life is more care-free as is. If we look at the relationship between master and servant we see a level of respect and trust.
While there was a Klala of Yehi Kennaan Eved Lammo, that is not a liscense to kidnap anyone. It is merely a Klala that he will be kidnapped. Ve’inu Osam wasn’t a Hetter for the Mitzriim to torture us and being a son of a Yefas To’ar is not a Hetter to become a Ben Sorer Umoreh.
