Personally, I don't agree. I see nothing wrong with women teaching. Preaching... I don't know. I'd have to research that. Still, I support women teaching.
But, it's their church and their choice. So long as they don't interfere with the government laws, the only people with authority to tell them what to do are the higher leadership (assuming they aren't independent).
BTW-I heard the pastor. He said that there were many other issues and that he, in order to show his Christianity, wouldn't bash her in public. Sounds like it wasn't just the fact that she was a women, IMHO.
