There are precedents, but they are pretty weak, for removing a sitting Pope against his will.
Most of them involved poison, which tells you something how long ago that was a going thing.
The only other case was during the Great Schism where the University of Paris was used to mediate between the two Papal camps. They tried to depose both and elected a third man, and ended up with THREE Popes and a mess that had to wait till the last of two lines died before sorting out.
Just a reminder, it has been much nuttier.
All true of course.
But it is highly unlikely that the current Pope will be forcibly removed from office or that a Schism might occur as a result of his political views.
A more likely (and hopeful) scenario is that his advanced age will encourage him to follow in the footsteps of his immediate predecessor and take an early retirement.
