I'm just speaking in terms of common English because I don't have a degree in critical theory. I do not view two places being prisons as making them equivalent, just as two places being states does not make them equivalent, they just have certain specific features in common that both make them fit that definition.

If someone said, for instance, that I don't support the ultimate destruction of "the state" in common language but rather a more specific and abstract definition of the "State" inherited from Marx referring to the apparatus that mediates class antagonisms, but that if one uses "state" to simply mean "government" then yes, I think there should always be a government, my reply would be "yes, that is correct". I can speak at length about how my desired government would be different from the existing one, but by their definition it would still be a "state" and that's fine.

It's important to be able to communicate in a way where people who are trying to understand what you're saying can understand what you're saying, even if there will always be concern trolls doing a Young Turks fear mongering routine (who only need to be accounted for in terms of combating them, which being understood by sincere listeners helps with)
