Quite simply, women teaching men in a church is an act of rebellion.

Acts 18:24 Now a Jew named Apollos, a native of Alexandria, arrived in Ephesus. He was an eloquent speaker, well-versed in the scriptures. 18:25 He had been instructed in the way of the Lord, and with great enthusiasm he spoke and taught accurately the facts about Jesus, although he knew only the baptism of John. 18:26 He began to speak out fearlessly in the synagogue, but when Priscilla and Aquila heard him, they took him aside and explained the way of God to him more accurately.
Thats a woman pastor teaching a man right there. Pricilla was a copastor with aquila. Even if you dont agree that she was pastor, you are still seeing a woman teaching a man there in the church.
