Some interesting tangential points being made.
1. I think DS needs to explicate a bit on some of his assertions, such that they can be more readily understood/critiqued. I think elaboration of how Mormonism is the true expression of American Christianity will be entertaining. I also detect a vacuum of understanding of non-RC American Christianity that seems to be filled with the usual, popular secular progressive prejudices.
2. It is absurd to mark fistful's comment as anti-RC. 90% of it is verifiable fact and only a small bit is opinion. (That opinion being that slavery, systemic gov't discrimination, and killing unborn children is evil.)
3. DS is very much correct, IMO, regarding much of American Christianity as now-focused and making contemporary political positions and issues part of its creed. But DS only gets it half right, when he points out how some American churches have become adjuncts to the GOP and various flavors of neoconnery. The half he misses are the mainline prot denominations (and some sub-sets of the RC) that have made the social gospel the sum total of Christianity. Feed the poor, agitate politically for them, and you are on the side of SJWesus. Another part of that are the black churches and their perennial agitation in favor of their own political and material interests.
Both sorts are cross-wise with Augustine & Two Kingdoms theology.
=============================
Getting back the the OP, what is heinous is the meddling in the RC Church by political facitons and the attempt to fracture the relationship between its hierarchy and the parishioners. I think many of the commentators to the article are correct that such agitation ought to result in Podesta's excommunication. But we know that will not happen, because much of the American RC church has already been co-opted by marxism and progressivism. We know this because RC policritters who espouse views directly counter to bedrock RC doctrine are not disciplined.
