I don't know what number is the accepted % of [Mark May]ty fans vs normal ones in any given fanbase. I think I've seen 90% good to 10% [Mark May]ty. Penn State is 10% good.....if that.
So even if this is true --- what is your opinion as to what drives such a stark difference?
I've visited every state in the country --- I've even been to 65% of the
individual counties (one of the more bizarre things on my "bucket list" is to try to visit all 3,142 counties in the United States). In my opinion, the state in the country that is most like Pennsylvania is Ohio --- and vice versa.
(1) Pennsylvania and Ohio share a 100+ mile border. There is no wall at the border. You do not need a passport at the border. Point being, cultures will bleed over borders.
(2) South-central, east-central and southeast Ohio, which are all dense with Buckeye fans, is strongly Appalachian culturally. Central and Southwest Pennsylvania, which is dense with Nittany Lion fans, is also strongly Appalachian culturally.
(3) Central Pennsylvania is isolated, yes. Plenty of hick little towns like that one from your anecdote: places where the native population rarely leaves. The whole state of Pennsylvania is not like that, however. There are tons of Penn State fans who live/grew up in non-isolated portions of the state: Pittsburgh, Philly, Harrisburg, Lehigh Valley, et cetera. Likewise, there are isolated portions of Ohio, plenty of hick little towns (south-central and southeast in particular). But the whole state is not that way.
(4) Both are generally blue-collar, rust-belt sort of states. Mining, coal, iron-working, et cetera: all highly important in the history of both states.
(5) High school football and football in general is HUGE in both states.
Given such, why would Buckeye and Nittany Lion fans be so fundamentally different?
