I disagree with your argument based on that text. Nowhere does the Bible say "thou shalt not ordain women". I agree with Murcielago's point that it is quite possible that such a prohibition exists only in the minds and on the agendas of church leaders. Saying that a women should not usurp man's authority is absurd in today's world.
That isn't the only text on the question, but we can start with that one. What do you think Paul was saying in that text?
Note that Paul uses creation-based and fall-based arguments to support his position, whatever that position may be.
If today's world is what makes Paul's statement absurd, then that illustrates the problem. Other denominations that have grappled with this issue ended up having to also grapple with whether they should ordain practicing homosexuals. Many would claim that in today's world, not ordaining such would be absurd.
For Adventists there is a greater issue: If today's culture mandates that we set aside some texts, then what about the Sabbath/Sunday issue? In today's world the culture is different than in Bible times, and Sunday is now a special day in society rather than the Sabbath. Must we be so rigid regarding the text that we stick with the Sabbath despite today's culture?
So what we need to ensure unity is a way to deal with Paul's statements that does not set aside the text because of today's culture. Unfortunately, this is a major weakness in the women's ordination camp, and that is a big reason why they have not been more persuasive.
