A friend of mine studied theology and said (when I remarked something similar) that that's a very Protestant perspective.

Catholicism has had a long history of people disagreeing with the pope. There have been antipopes, wars between Catholics and the Papal State, theological factions where the Pope is just one participant, etc. . Papal infallibility is a very recent doctrine, and it only applies when he is speaking ex cathedra, which is rarely. Many Catholics don't adhere to it, and many only consider it a matter of worldly convenience against schisms.

That said, there are no AI generated images of Trump wearing Papal vestments or overseeing the holy mass. Trump is not presented as an anti-Pope, but as an anti-Christ.

Hannity doesn't call himself Catholic, and that's also not exactly true.

As an ex-Catholic: Catholics only have to accept things that the Pope says ex cathedra, which means he has to make a formal, official statement speaking for the Church, not just expressing his personal views. You can also criticize the Pope's behavior, the Pope is still a sinner like everyone else, only Jesus is without sin. That's how Catholics deal with all those mideval popes having gay harems and stuff, and it's also how they deal with all the times the Church was wrong, like claiming that the sun revolved around the earth.

Infallibility has to be limited in scope or it wouldn't be possible to weasel out of things.

Well, technically the Pope is only infallible with respect to cathedral matters:

The definition of the doctrine of papal infallibility was promulgated on July 18, 1870, in the dogmatic constitution Pastor aeternus (Latin: “Eternal Shepherd”) of the First Vatican Council. This document states the conditions under which a pope may be said to have spoken infallibly, or ex cathedra (“from his chair” as supreme teacher). It is a prerequisite that the pope intend to demand irrevocable assent from the entire church in some aspect of faith or morals.

That's not really true at all though. The pope isn't always right, without exception. He's only infallible on matters of faith or morals, and on doctrine which is stated as being the view of the church and which invokes his supreme authority. Popes are capable of being wrong, making mistakes, or sinning.

I’m sorry, but this is BS.

The Church is run by people and people are fallible.

Bishops sign their names with an upside down cross to remind themselves that they are sinners who make mistakes.

A shocking number of saints are people martyred for standing up to the Church when it had become corrupt.

It’s a Catholic’s duty to stand for what is right.

It is a lot more nuanced then that, but for many catholics that is how it is.
