Great game, excellent story, graphics, gameplay. If you let little things that some might consider 'progressive' or 'diverse' bother you too much, just give up though as its hard to know what else might not be to your taste.

I hate having politics, especially anything SJWish shoe-horned into games but this is a post-apocalypse setting where they're trying to show a different type of culture and tribal system, don't expect it to make perfect sense. In many ways its the opposite of what SJWs would like as its a fairly colour-blind society, i.e. race doesn't have very much to do with people's identities (and the lead is a pale skinned red-head, one of SJWs key targets for erasure). Imagine if instead the game had originally been shown having a red haired heroine but internal pressure saw them replace her with a black character, that character had a prominent same-sex love story, and her black tribe was being persecuted by a tribe of white people tattooed with skulls and eagles - because if SJWs were designing it you know that's what you would have gotten (mind you, could still happen with the sequel).

If you look for things that 'might' be SJW-tinged you'll find them, the same way SJWs always find things that 'might' be racist, or 'might' be offensive. My advice is give game developers and tv show makers the benefit of the doubt when there's a little bit of progressive content and remember there's still a big difference between someone having left-wing views and still being a sane, decent person and them going full SJW. If its actually SJW-driven it will become so heavy-handed so quickly that you won't be thinking "Is this hyper-left trash?" the answer will be self-evident.

If Horizon doesn't suit you, try Far Cry 5. I found the revelation that the game is actually full of right-wing good guys a pleasant surprise.
