Okay, fair enough; if you find people who keep saying "liberty" while they are busy restricting what others can do, and I think that's not terribly far off the mark here, then even if they are genuinely deluded and intend for liberty to mean the same thing that everyone else thinks, operationally by "liberty" they mean "oppression of everyone who doesn't follow our favored rules".
I hesitate to use operational definitions in this manner, though. I'm not wholly opposed, but I think many things that many groups do don't withstand the scrutiny of operational assessment.
The "facts don't care about your feelings" crowd on the right seems to define "facts" to mean "my feelings" and uses "whatever the libs say regardless of evidence" as the definition of "your feelings".
The diversity, equity, and inclusion crowd on the left seems to define "diversity" to mean "people who think like us regarding social justice" and define "inclusion" to mean "exclude people who used to be included and vice versa".
Trans advocates (on social media) seem to define "just want to be left alone" to mean "berate everyone who won't unconditionally accept our modifications to the idea of gender, our reconceptualization of fairness in sports, the cancellation of every prominent figure who says something that can be perceived as negative in response to something we say, etc.".
Most MGTOW's (on social media) seem to think that both "going their own way" and "getting tired of women" mean "incessantly and bitterly pining about not having the romantic relationship with women they're constantly dreaming of".
I'm not convinced that a better way isn't just to take people at their word with standard definitions, point out when what they say doesn't really match how they're acting, and then ask: so, even though you're talking about this wrong, do you still have a good point lurking in there, or is it all just words standing on their heads, to use Gimli's turn of phrase (courtesy of Tolkien)? Do you want to fix the discrepancy by meaning what you say (and changing your actions) or by saying what you mean (and changing your language)?
