Well, I'd note a couple things....
First, this is an Ohio State board, after all. And, with all due respect, "outsiders" are perfectly free to comment about Ohio State in negative ways that aren't trolling - that is to say, are arguments backed up by reason and/or stats...
Second, where did Muck denigrate your school? My read on it was that Muck simply supported his contention that your remark about Nebby being "above you guys as you are above us now" was not correct (in his view). I don't recall seeing him say "Nebraska sucks!' or "You're a goat fucking corn shucking putz" or any such.
Whether you choose to engage in your own counter argument or not is not up to me. If you feel it's "validation" of something ridiculous, I'd suppose you should just let it go then. (And I don't say that to suggest you're at some "fault" here or toeing some line which might result in a ban or any such silliness)
