I think different cultures can share the same reality, though filtered through different lenses.
If two people from different cultures watch the same movie, one finds it ok and the other offensive and disrespectful, that's a shared reality filtered through different cultural backgrounds. Even if either version of the movie is dubbed, censored, or altered in any way, there's still enough common or shared material that a discussion can be held.
If two people had completely different experiences and watched completely different, tailor-made movies, then there's very little for them to discuss or even disagree with. "I haven't watched your movie", "I haven't watched yours either", "Mine was better", "I guess... I wouldn't know, I thought mine was cool", etc. No shared reality.
My point, which admittedly my last message didn't make at all, is that "different shared realities" is not a new thing. The concept is what would have been referred to as "different cultures" throughout most of human history.
Different art, politics, passions, fears, identities, and myths is what cultural variety is about.
If you and I watch the same movies and listen to the same music and follow the same politics and share the same dreams and worries, I don't think it's reasonable to say that we are from different cultures.
What is being described as a "shared reality" in this thread feels more like globalism and less like something obviously positive or worth protecting.
I'm all for more cultural variety as an expression of individual differences.
