Yeah, I'd say motivated thinking.
Comments like these are not helpful. Especially not on a highly politicized topic such as the one the two of you are discussing.
I don't know if it's enough to matter, but I only mentioned motivated thinking because Villiam brought up the possibility.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
