The partial God and gender equality

Christianity has always upheld the notion that God does not have favourites. That he loves and cares for everyone equally.  However, the origin and evolution of Christianity proves otherwise.  

Right since the beginning of God's intervention in human history, as per Christian tradition, God has always been on the side of a particular group or nation.  The old testament is a fitting proof that Yahweh always preferred Israel over and above all other nations and people.  He was on their side, against the Egyptians (when in exile), against the Canaanites (on their return), against the Jebusites (on behalf of David)... Yahweh always chose the Israelites.  

Even in the new testament we see this continued privilege of Israel.  Jesus, the son of God is born a Jew.  In Israel.  For that matter, Jesus himself was partial all his life.  He took the side of the poor (against the rich), the religious ignorants (against the religious authorities of his times), the Jews (rather than side with the political rulers of the time, the Romans).  None of his chosen twelve was a non-Jew.  He barely preached outside Israel or to any non-Jews.  Rather his treatment of Syro-pheonecian woman can always be used as an example to prove his preferential option of the Jews, over non-Jews.  

However, there is one thing common among the many preferential choices that God made all along history.  He chose to be on the side of the poor, the underdogs, the marginalised, the weak and the oppressed.  He stood by those who needed support and guidance.  Who by themselves would not have been able to make it.  So that makes me wonder, if his choice of men alone for the chosen twelve or for active apostolate, was an indicator of who was the weaker gender.  Who it is that needed support and accompaniment?  Going by God's preferential choices and the reason for that choice, it certainly looks as if he considered woman as the more stronger and able gender!  If there was someone who needed to be guided and supported it was the man!!  So much for thinking that man is the superior of the two sexes!!
