Going back to the early days of the papacy, I think that what many conservatives found so alienating was the way the pope stated that he wanted to change the conversation away from abortion and marriage and the issues of social Catholic conservatism.
I think that a lot of people took that to mean that the highest echelons of the Church did not had their backs anymore.
It is one thing to be a pariah on these issues from society in general when conservatives stick their necks out on these issues in defense of Church teaching and morality. But t is very disconcerting to see that this is no longer a deep and abiding interest of the papacy itself in standing with conservatives on the issues of the day.
It is never easy to swim upstream against the currents of culture, to be labeled as a hater and a bigot just on account of putting Church belief over personal belief.
And virtually every conservative, like everyone else, has personal associations with homosexuals, with divorced, with people who have vehement disagreement with Church doctrine. To the extent that conservative Catholics choose to talk about these things at all, it has meant putting themselves on the line, and subjecting themselves to friction and vehemence and accusations of self-righteousness, hypocrisy,heartlessness, etc., etc. etc.
With the Church’s assurance that this was the path of Christ, the teaching of Christ, courageously advocating for the Church was tolerable. To see Pope Benedict, for example, being treated with the same derision and contempt when he took his stance against condoms as being the solution for African AIDS pandemic, people were given the feeling of solidarity with the Church and the papacy itself here. Conservatives were not alone in the difficult and often demeaning venture of standing up for a higher morality, against the morality of the world, which the world itself advocates as a higher morality.
Right from the beginning of his papacy however, Pope Francis re-aligned himself. Conservatives were left alone on these issues, as the Pope became the media darling for leftist causes.
