voluntary submission to comp or egal positions

Complementarians and egalitarians both claim that their interpretation of the Bible on gender issues is the biblical position. I have read a number of blog posts and other writings from complementarians which imply, if not directly state, that those who do not hold to a complementarian position are in error, not following biblical teaching properly. I have to assume that some egalitarians would say the same about those who disagree with their position.

Related to this issue is the question of whether or not those who believe that their position is biblical believe or teach that following their position is voluntary. For instance, do "biblical complementarians" teach that married couples in their churches or spouses in marriages can volunteer to live by complementarian principles? We could add to that question, "Can they volunteer to live by those principles and remain biblical?

Some appear to take the position that it is appropriate (biblical?) to voluntarily choose to follow a comp or egal position. Is it the teaching of standard (whatever that is) comp and egal teaching that choosing to follow that teaching is "voluntary"?
