A thousand years seems like a random arbitrary number. Judaism has been around for a lot longer than that, and Christianity has been around for a bit more than 2000 years. So if you believe the discrimination is present then it has been there for a lot longer. Much of the implied "discrimination" around Judaism might be more a result of middle eastern culture. Christianity might be more about the long time assumption that women should not have leadership roles within the church. That one is changing quite quickly in recent years and many congregations have women on the church council and even as ministers. Regarding Judaism the bible is full of instances where women have served important and powerful positions. The book of esther cor instance is about a Jewish woman serving as a queen. Rahab hid and saved Jewish spies. The birth of Christ was first told to women and Christ first appeared to women after his resurrection.
