Your reply is not exactly born out by the evidence.
As you can see Moses allows the purchase of humans as permanate property to be handed down as an inheritance to future generations as long as they were not Hebrews.
(**Leviticus 25:44-46 NLT)However, you may purchase male or female slaves from among the foreigners who live among you. You may also purchase the children of such resident foreigners, including those who have been born in your land. You may treat them as your property, passing them on to your children as a permanent inheritance. You may treat your slaves like this, but the people of Israel, your relatives, must never be treated this way. **
He allows men to sell their daughter for the purpose of pleasure.
(Exodus 21:7-11 NLT)
When a man sells his daughter as a slave, she will not be freed at the end of six years as the men are. If she does not please the man who bought her, he may allow her to be bought back again. But he is not allowed to sell her to foreigners, since he is the one who broke the contract with her. And if the slave girl’s owner arranges for her to marry his son, he may no longer treat her as a slave girl, but he must treat her as his daughter. If he himself marries her and then takes another wife, he may not reduce her food or clothing or fail to sleep with her as his wife. If he fails in any of these three ways, she may leave as a free woman without making any payment.
And he allows slaves to be beaten as long as the blows do not immediately kill them
**(Exodus 21:20-21 NAB)
When a man strikes his male or female slave with a rod so hard that the slave dies under his hand, he shall be punished. If, however, the slave survives for a day or two, he is not to be punished, since the slave is his own property. **
Clealy, slaves can be purchased, beaten, I assume raped, and passed on as property. This is shameful considering the treatment the Hebrews just escaped.
