I can agree with you on how our presidents shouldn't all just be practicing Christians, considering this country is supposed to be tolerate of other religions and people came here so they could practice freely and be accepted as well.I wish that religion was completely separated from the government but, that won't happen. Many people live life and make decisions based on their faith.
As for sumission of wives to their husbands, I think only extremely conservative religious people of christianity do that. I'd laugh in my husband's face if he mentioned me submitting to him. But I do feel that a lot of Christianity in America is hypocritical so, I'm not a strong follower just observer.
