Some random, anecdotal thoughts:
I once heard that in the US, the Dems and Republicans have influence in differing sectors:
Republicans - manpower-heavy sectors like the military/Pentagon, agriculture, extraction/energy
Dems - informational sectors like the media, finance, tech, education
Right now, the tech and finance sectors are probably the most thriving sectors in America, and because of their very nature (informational), they're able to rapidly push their values. Considering these industries are situated in highly diverse, wealthy, coastal urban areas, what gets pushed seems foreign and imposing to small town middle american conservatives, triggering more backlash.
I wish I could find the article, but I had a good one that shows 'wokeness' is a cultural elite symbolizer. In fact a lot of people will use the 'language' of wokeness but not actually buy into it. Being "offended" seems like a type of virtue signaling more than anything else, the polar reversal of late 90's, early 00's "extreme" culture ("you can't offend me! even with your goatse and edgelord racist jokes").
The culture war that's mostly been apparent to me lately is the working class vs. professional class divide. When I look at my friends and people I associate with on a regular basis, almost all have at least a 4 year degree and work in Dem-focused sectors. Working class people (usually those in the trades, who around here make some very good money and also are strong Trump supporters) I talk to tend to have a lot of suspicion of the professional class and live in their own media/social/interest bubble (and yes, there's a whole cottage industry for conservative grievance - look at the people turning a mediocre chicken sandwich into the paragon of high-class dining). It's like, in my personal experience the people I'm friends/acquaintances with is certainly diverse (in terms of the big corpo HR definition), got people who are lbgtq, varied racial/ethnic backgrounds from West African to Sephardic to Peruvian Chinese to Indian and Japanese expats, but barely any salt-of-the-earth working class types. I just can't seem to relate to them on political, cultural, hobby, levels.
