In my experience trauma manifests itself in a variety of ways, including more supportive of others. The crew would be unified in their trauma so commiseration and camaraderie would be something I would expect.
And even if that isn't our experience, wouldn't we hope that the more evolved humans would have increased measure of compassion for their traumatized crew mates? Wouldn't we want to see that supportive attitude and openness even if it is outside our own experience? To me, that's what I want. And, perhaps this is letting the curtain a little bit much, but that's what I hope humans will be like some time in the future, rather than the personal missmash of platitudes and being talked down to in my own history.
I dunno. Lots of people make fun of early TNG for having silly ideas like humans will have "grown beyond" grief. I'd rather have character be relatable and flawed within a semi-utopian setting, rather than being "aspirational" in some sense.
I know it's not everyone's cup of tea, but I feel like the camaraderie on Lower Decks feels so much more real, because the characters can be selfish shits, but they are also capable of being great friends to one another when it's pointed out how shortsighted they are being.
