Yes, if you’re looking for a simple way to express the concept, that’s a good way to do it.

Poppler’s formulation isn’t meant to be simple. It’s meant to be complete.

If I’m teaching an end user how to use the program I wrote, I’m not going to explain the code line by line. But if they ask me why it can’t do some random and largely impossible thing that they want, I absolutely need to understand the code in order to explain why that isn’t possible.

Understanding Poppler’s formulation allows you to address the many ways in which people will try to undermine your simplified version. An example I’ve used elsewhere in this thread is the idea that “We can’t ban Nazis from our platform because then we’d have to ban all forms of political expression. Otherwise we’re just playing favourites.” It’s the “If you censor me then you’re the one being intolerant” argument, usually strapped to a slippery slope fallacy about how you’ll never stop censoring stuff once you start. And it’s very, very effective. Lots of well meaning people who are not Nazis or Nazis sympathizers can still be very easily swayed by this logic.

Poppler cuts through all that. He gives us a clear and definite criteria for what ideas are acceptable and what aren’t, and an ironclad justification for why. The theory he lays out is essential knowledge if you ever want to successfully defend the position expressed by “Tolerance is a social contract,” or the “Nazi bar” analogy, or any other excellent ways of introducing these ideas.

You don’t have to start with Poppler’s paradox, but sooner or later you will need it.
