The "sweeping generalization" is referring you to not responding to any counterargument. Your response was always just "I love tom herman"
My argument did not devolve in any way whatsoever. Its a basic logic argument followed by a conclusion: OU wining helps OSU - I assume you like OSU more than Tom Herman - You must root for OU.
I didn't think that was hard to follow. You simply cherry picked the final conclusion and left out the entire argument preceding it. I would say that you are the one who's argument devolved.
