xkcd #3084: Unstoppable Force and Immovable Object
(imgs.xkcd.com)
Title text:
Unstoppable force-carrying particles can't interact with immovable matter by definition.
Transcript:
[An arrow pointing to the right and a trapezoid are labeled as 'Unstoppable Force' and 'Immovable Object' respectively.]
[The arrow is shown as entering the trapezoid from the left and the part of it in said trapezoid is coloured gray.]
[The arrow is shown as leaving the trapezoid to the right and is coloured black.]
[Caption below the panel:] I don't see why people find this scenario to be tricky.

I have seen the current US sitiatuation be described many times as a unstoppable force (Trump) going against every law and institution, but they are characterized as unmovable, because they refuse to exert resistance to Trump advances.
Edit: a random blog using this metaphor before the election. https://yaschamounk.substack.com/p/the-danger-to-american-democracy
Given how inaccurate that metaphor is, I can say with near certainty that has nothing to do with this comic.
