In both threads, there’s the underlying theory that people have reasons for doing things.
If you grow up in Pillowton and the Pillowton Cowhawks are the pro baseball team and, as you’re growing up, everyone is telling you that you need to support the team, wear the team colors, go to the games, cheer for your guys, and push new and younger people into doing the same - well, that’s what you do.
In the cities, for example, you’re told often and dogmatically that gay people are good, kindly people, who are being attacked for no reason, and who need to be supported. In the rural areas, you’ll be told often and dogmatically that gay people are people who live in sin, mocking God, and act at the devil’s orders to try and corrupt youth and lead them away from God’s laws.
Functionally, neither of these viewpoints is objectively correct and, more importantly, very few people have taken either of these viewpoints on through conscious consideration of the merits or pros and cons.
On this forum, perhaps, the average person might have a justification for their view. But even there, did you have the viewpoint before or after you found and understood the justification? Among the average middle schooler, what percentage of them do you think looked up a debate between a variety of philosophers on the subject and watched through to hear the different angles on the topic, went out to a nearby hill and sat on it staring up at the sky in consideration, and came down with a personal answer when they came down from the hill?
Our brain likes things which are familiar and that we’re already favorable to. It will always prefer an answer or justification that allows it to continue the status quo. If you backed gay people before you got to college, you’ll probably find a justification that allows you to maintain the view, and not challenge the view. You’ll be inclined to be dismissive of counterarguments and naturally favorable to ones that are already on your side. Years later, you’ll think that you made a clear decision on the topic and that you were completely rational in how you arrived at your current place in life.
And yet, there’s no reason to believe that you’re so different from a person who was raised 500 miles away in a red state, got similar grades in all their classes, and went to a college in Oklahoma. Somehow, that person will have come to the opposite viewpoint, through all the same processes as you, with all the same innate ability, and similarly come out thinking that he arrived there through full rationality and deep introspection.
You would not see the geographic divide on views if logic was really the underlying factor.
If you can see it on a map and it’s not a question of something like “Should the government give money to the rural folk or the city folk”, with a concrete and practical relevance to geographical considerations, then it’s tribalism, generational indoctrination, and propaganda and not anything else.
