(This doesn't seem to follow. Are you supporting women speaking, teaching and preaching in the assembly? I thought you were arguing for the proposition. I will continue in that vain.)
The Bible does not contradict itself. (It cannot be both A and ~A). For a woman to speak in the assembly and to preach/teach with authority over adult males is in direct violation of the doctrines of 1 Timothy 2 (and 1 Corinthians 14). A church/assembly of believers that permits this shows ignorance and/or blatant disregard for the clear teachings of scripture. (e.g. Twisting [diakonon] to mean women can violate prohibitions against speaking/preaching/teaching).
For though we walk in the flesh, we do not war after the flesh: 4 (For the weapons of our warfare are not carnal, but mighty through God to the pulling down of strong holds;) 5 Casting down imaginations, and every high thing that exalteth itself against the knowledge of God, and bringing into captivity every thought to the obedience of Christ. (2 Corinthians 10:3-5)
It is a "high thing that exalteth itself against the knowledge of God".
Paul said a lot of things ~ and you and I both know that what might seem to be a contradiction to mere men is actually an astute insight revealed by God ~ just that we are too weak to understand as yet.
