I live in a deep red county and I can tell you this is not the case. I won't say there are not some guys that just want to 'roll coal' because they think it looks cools, there are, but that is true of every strange hobby out there, in terms of numbers they don't matter.
The rest of the people not buying EVs are doing it because they
1) Don't have the have the capital or credit required to purchase a 'new' anything, they are in the used market and the used EV market does not have the products they want.
2) They are actually hauling pigs, cattle, hay, etc around at frequency and the only EV that really is a good fit for that is the Silverado and it aint affordable
3) They live in really old housing stock, they have things like 60AMP and 100AMP electrical service and even they can shoe-horn in a L2 charger, the performance would cramp their life style at least a couple times a week. Normally yeah mom and dad can use the cars during the day and charge them over night but on Friday night John Jr borrows the car and is out to 2am with his buddies, so yeah its actually not ready to take Susan to her tap lessons 30miles away Saturday AM.
4) They don't really see much advantage, the TCO isn't that different. They are still at the filling station often enough anyway, they still got lawn equipment, tractors, backup generators etc, and so they are are carting 30gal diesel tanks and 5 gal gas cans around in the pickup bed anyway. The folks in passenger cars gotta get groceries and house hold items, there are gas stations near the Food Lion, Dollar General, and Walmart anyway so it really takes no additional time. Even if over 10 years they might save a few $100 with a base model EV over an economy ICE vehicle the familiarity of ICE is more appealing.
BEVs are getting better, Hybrids are getting much smarter and better and importantly simpler, Honda's inline stuff in really does not add that much complexity. I see people getting either BEVs are Hybrids as a 'second' car all the time around here. Decisions are being made very rationally and at the margin. The media and BEV enthusiasts keep wanting to insist we are at parity, but really we are not. 10 years ago the suggestion BEVs were 'just as good' was laughably stupid, now its is very nearly true and even is true for many people/use cases. Its getting there and people will switch 'better'/cheaper is achieved. They are already switching. It just needs a little more time.
