So are your lectors going to form a special class that will demand that the Church allow them to stay in the sanctuary?  Or will they leave or refuse to read because they have been denied a special right?

The whole progressive movement is grounded in labeling people and demanding special privileges for those that are different in a well-intentioned effort to unify.  But when people are labeled and singled out for special attention, that is de facto divisive (that's why "diversity" efforts are misguided).  

Blacks should have no beef with the Church; the Church has no duty to make a special effort in their political causes.  People with same-sex attraction, at least, have a legitimate beef in that the Church expressly disapproves of their chosen use of their sex organs.  But when your core teaching revolves around male-female, procreation, parents raising their children, and the like, it's for the person to change not the Church.
