The toxicity of this form of in-group Evangelization-by-Being-a-Jerk is summed up in the word “Them”. All it communicates is “Get a load of the non-Christian vermin not being Christian! Amirite?” It is, like so much American conservative Christianity, ordered not toward communicating the love of God, but to reinforcing Unit Cohesion among proud bullies who simultaneously radiate Olympian contempt for Outsiders and pity for themselves. It’s a huge turnoff to anybody approaching the Faith from outside. But since the goal is to drive away the Impure, the Greatest Christians of All Time see that as a feature, not a bug. They seek a Church that is an exclusive club, not a sacrament of salvation to the world.
The distinction between this mentality and that of the Pope’s is that the Pope understands that we no longer live in Christendom. We are back in a pluralist society in which Christians have to earn respect and not simply take for granted that we are Top Dogs. Conservative Christians are frustrated and bewildered by that fact. It’s why so many are drawn to the MAGA cult, whose core message is “We deserve to be lords of the earth and They are taking it away from us. So strike back!” (See, for instance, Stephen Miller’s blubbering self-pity on The Ingraham Angle–and note that Raymond Arroyo, Catholic and Ingraham sycophant, is right down there in the corner because EWTN is just FOX with smells and bells.)
It is not a message native to Christianity (which began life as a despised sect regarded as neither fish nor fowl and which won hearts and minds by impressing its neighbors with love, not nihilistic power grabs.). But racism and nationalism and political designs have screwed over the minds of millions of self-proclaimed Christians who have turned Jesus into a totem for American nationalism and white supremacy. Unsurprisingly, they hate this pope because he has no interest in serving their dreams of power and domination and continually ignores the whole Fortress Katolicus dream they cherish. He constantly leaves the fortress and does what the apostles did and what Jesus commanded, going out in the highways to bring the gospel to the poor, weak, and broken. He has no interest in the mockery of Them and is a standing rebuke to the entire Fortress Mentality.
