I agree, but poking holes in why they're excluded is important, because it let's you have this exchange --
"You can't argue with the math!"
"Well, hold on now, I think you left a whole bunch of things out!"
If you don't know where the problem in the math is, despite there being an extremely obvious problem, many people will ignore your objections. That's why they use math, to paper over their obviously poor behavior.

Being able to strip that bare is useful.
