The scope of what you're considering to be their "ideological guns" is very historically recent. Before the Southern Strategy [0], the things that people typically associate with these "hicks" in rural parts of the US were not politicized; most of these hot-button ideological issues were considered to not be the domain of politics (e.g. abortion).
In fact, the people who were the first "rednecks" would most likely reject all of the fascist bootlicking that goes on for most conservatives (not that neoliberal bootlicking is better, just less prevalent; I don't see hordes of foaming-at-the-mouth Biden supporters screaming adoration about Biden with some goofy flags and apparel on the street corners, while I still see the Trump folks doing the same cult worship of their new "god"). The original rednecks were miners who violently opposed capitalist exploitation [1]. This culminated in the battle of Blair Mountain [2], in which miners living in exploitative conditions violently rebelled against the authoritarian private police (the "Pinkertons") in their attempt to form a union. This is also the first time that aerial bombardment is used on American soil (preceding Pearl Harbor).
Needless to say, I think the original "rednecks" have nothing in common with those who pretend to espouse some sort of "rural identity"; the original rednecks would not have looked to the state to force their own restrictive ideas of living on other people.
It's fine for people to have their own opinions about these things, but when these people who stick to their ideological guns do so in the face of facts (e.g. all of the cult-of-trump people who intellectually contort themselves to see him as some skilled businessman when he has a history littered with business failures, including losing money on a casino!), it's a little difficult to respect their opinions; this is especially true when their opinions are incoherent (e.g. the GOP celebrating Goya and that my pillow guy for "getting involved in politics" when it benefits them, while deriding companies looking to boycott states that plan to impose Draconian voter suppressing laws to "stay out of politics") and involve restricting the liberties of other people to comport with their own strict world view (e.g. restricting the right of other people to get same-sex married, as though that is somehow an "attack" on hetero marriage).
Ultimately it's about being able to accept new evidence and change one's mind, which I think these people who vote against their own interest (hicks or not) are not wont to do. Just as not all people in the GOP are fascists, but all fascists vote for GOP candidates, not all people towards the liberal end of the political spectrum are open to new ideas and changing their mind, but all people who are open to learning and change are on the liberal side of the political spectrum.
