Not really, you look at someone like /u/eaturbrainz (a unironic communist), /u/summerspeaker (a unironic SJW trans-unicorn) and it's incredibly clear they care about people and have a friendly disposition, even when ranting.

Then you look at someone like /u/darwin2500 and it's clear that he doesn't. Always sophistry, always snark, mocking whenever possible, baiting people into getting banned and throwing the mods at anyone from his outgroup the second an opportunity appears…

You look at what kinds of stuff people talk about, whether or not they only talk about one thing all the time, how they react to fellow members requesting advice or talking about someone else (I can talk about eg. game modding or MTG or my life with no problems with a political enemy who is friendly but I can't talk about anything with Darwin2500)

Of course it's much harder than going by some formalized heuristic abusable by psychopaths, prone to false positives and frankly harmful for almost anyone involved, as most people that do fine still are comparatively psychically mutilated because of it, even if they don't realize it.
