And given that the bishops until now have largely lived lavishly, I could argue that they have no credibility when they demand that we welcome refugees and be mindful of the poor. Many bishops continue to live lavishly. 

In other words--the bishops were deficient in their living and following Catholic social teaching just as they were deficient in following Catholic moral teaching--therefore I can ignore them and tell them that they have no right to tell me anything about caring for the poor until they get their own houses in order.

Here is my point: instead of blaming your dissent on Catholic moral teaching on the bishops, why not just man up to the fact that you dissent?
