There are only two ex cathedra dogmas and they are both about Mary.  Period.  You can dance and do a jig but those are the facts and they are not changing because you do not like them.  

Dogma and Ex Cathedra are not the same things.  Some things are teachings and called dogma but can change because they are not official Ex Cathedra Dogmas.  Any teaching of the church or tradition can be referred to as a dogma but most can be changed and many have been.  

Your highly defensive final statement regarding women being ordained priests is proof you are not convinced yourself that this rule excluding women from priesthood can't be changed.  And definitely proof Christ wanted women discriminated against is necessary to continue excluding women because otherwise we sin continually and continue to weaken.  There is no proof Christ desired Bishops to treat or ordain women any differently than men so we do sin while we continue this bias.  And the Gospels are my proof.
