It's great that they aren't procreating then.

I have this theory that negative affinity groups (a term I made up for groups based on antipathy for something or someone) have a tendency towards toxic behavior. When you gain connection and social clout for dunking on someone or something, there's very little incentive to be fair to them or show any kind of nuance.

Contrast with groups with affirmative goals or a defined object of interest. The positive groups can measure progress towards their goals or new and interesting perspectives on their objects.
