This is a great topic, GS. Many women are offended today and don't like the word submission, and it all goes back to the problem that started in the Garden.
I can't think of any plausible medical reason why the Lord would choose to have a woman wait 80 days after having a female child, and only 40 days for a male child... but who knows, maybe someday science will come up with a very plausible and incredible explanation?
Many such things that we see that God had the Israelites do had a good reason behind it, even if we are not by law required to do those things any longer.
Submission will always remain a hot issue to those who have not learned the beauty and joy and rest that come with submission.
I am thankful that I have learned that true peace and joy in a home come when I am not trying to undermine my husband's leading, but when we work together, and I am grateful and willing to follow his godly leadership. It is a beautiful thing when you understand it can work just as the allegory of Christ and the church.
Now I don't believe that a woman has to wear a skirt and not cut her hair, as you do, but I respect your position on that because I know it is the culture you are in.
Being a part of that culture for a big part of my life, I have known far too many women who relied on their outward appearance, and never tended their inward and who fit the description you speak of (no pants, no cut hair etc.). And I have known far more women who may trim their hair and wear a pantsuit, but modesty is high on their priority list and they would never wear or do anything to bring shame or undue attention to themselves.
True modesty begins in the heart, and it cannot be replicated any other way.
I know my post covers a wide range of topics here, but just my 0.02 cents worth
