You would be right, in my opinion, if all you had to work with was Numbers and Leviticus. But the Bible is far more than just these 2 books, especially when you consider the Gospels. Nothing is more engaging than Ruth. Nothing more appreciative of the relationship between men and women than the Song of Songs. Nothing is more intense in its devotion than the Psalms.
There is another thing that I always like to consider. The entire Bible is a history of how God dealt with a certain group of people. By the time Christ came along, we were treated much differently than at the beginning.
You would have a better case, I think, if you studied what the Bible does about women.
