I absolutely think it's fair to use the term hivemind. The base class of hivemind, community, is generally a bit more open-minded.
A community might say "Well, you really ought to back up these assertions, because they may be a bit unsettling for some folks". It may not even react predictably to such things, being more liberal than expected.
By contrast, a hivemind will downvote and write them off as "unsubstantiated and creepy", fail to provide guidance, and perhaps even lash out at the folks identifying it as the less-friendly version of its parent implementation.
