Because it is our Church as well.  We worship at it and we contribute to it.  We hate our right to have our voices heard about these things.  
Let's just give some examples:
1.  Apparently until this year, religious sisters weren't invited to the main Vatican session for religious.  In this case these women are directly affected by these regulations but had say in them.
2.  A pastor can basically do whatever he wants with a parish.  He has the right under Canon Law to act as a dictator.  Again lots of laywomen who worship at the parish can be ignored.
3.  Women are affected by requirements for marriage and the other Sacraments, parochial school registration, annulments, etc.  Laypeople are rarely consulted on these things.  
4.  There are charities, hospitals, etc. run by sisters and laywomen.  These women find themselves on the losing ends of arguments because clerical collars always win out.  One sister in AZ was excommunicated for authorizing an abortion for a sick woman.
