Some groups are very much homogeneous by design. Religious dimwits and police come to mind. I judge the morality of those groups all the time and I sleep fine. Meanwhile I feel kinda bad for swiping whichever way is ‘reject’ on dating apps. I’ll agree that is not right for most groups. But groups founded on hatred (police and rekigion) or for the purpose of being obnoxious/attention seeking (ABATE motorcycle chapters) can absolutely be generalized.

Now keep in mind we’re discussing in a thread where the top level comment was from an admitted Nazi sympathizer.
