I understand where your reaction is coming from, as I can see both sides of this issue. The reason I suspect that post was given a hostility warning was that the statements made, although satirical, could easily be seen as intentional provocation. Phrases like "shoved in a gulag" or "Schine-sucking yes-men" are likely intended to have a cynical joking tone to them, but come across, to me at least, as threatening and hateful speech. It's probably not meant to be taken seriously, but it is being used as a form of shaming (known in the sports industry as hazing), which shouldn't occur in any situation, especially one that is meant to be welcoming of new members.
