Literal interpretation makes sense for women in the pulpit. Paul directly compares and uses the created order of God to defend and support his thoughts. The "dress code" is written in a way that could be seen as Paul's personal thoughts. And besides, there are very logical and physiological reasons why women should not be pastors. They were not made to be pastors and as thus have not been properly equipped for the task. This does not mean that women are terrible. It just means they are different.
Though, to be fair, I don't consider Paul authoritative (and I don't see support for him being authoritative within his works like some do), so this argument is moot in the fact that I do not feel the need to subscribe to all of it (though I do subscribe to all of it).
