The church has changed throughout its history as it has made bad decisions, even about matters of Doctrine.  

No church can be considered Christian if its laws demand that its leaders & laity abuse half of its people's human dignity.  This breaks Christ's greatest commandment to love God above all else & treat our neighbor as we wish to be treated-including women.  

Sexism -keeping  women from anything they are fully capable of doing or performing, has always been proven to have extremely harmful results.  These include:  poverty, violence, slavery, child abuse, torture, forced illiteracy, & even terrorism.  When religion shows the example of women being treated less sacred than men, as by our unequal & unjust ordination rules, these ills increase even more. 

It is right to fight for our church to become what Jesus taught for us to be.  Sexism is hatred just as much as racism.  The church practiced both of these evils for centuries.  Would you have the church own slaves again?
