"They could listen to the bishops, the traditions, the magisterium, etc. and then articulate adequately their disagreement."  

Where?  Where is the forum that lets this kind of give and take discussion take place?  I understand Vat II suggested diocesan synods, lay councils - but where are they?  How many diocesan councils have been held and how many allow a discussion of doctrinal issues?  We need a place in which real discussion is allowed to occur and a requirement that both bishops and lay set the terms of the discussion.

It is going to be interesting to see what happens regarding the 2020 Australian national synod.  Will they really allow people to talk about issues that divide - contraceptives, sexual expression,  respect for and inclusion of LGBT people in the life of the parish, a voice in selection and oversight of bishops, much larger roles for women, the need for more priests and the issues of married and female priests?  Probably not.  But this is what needs to occur.
