I'm glad you mentioned this, because I'm looking for a related term.

Sometimes in discussions (often political ones), I see this pattern:

1. Person A and person B are both members of group G.

2. Person A advocates view P.

3. Person B advocates view Q, which is logically incompatible with P.

4. An outsider concludes that some persons in G are logically inconsistent, because "G has members who believe both P and Q".

Is there a name for the fallacy in step 4? It reminds me a little of kettle logic[0], or the association fallacy [1], but it's clearly different.
