Unequal treatment of people on things they were born with is unfair hence wrong, period.
Logically it applies is all directions, no matter if some people deem specific forms of unequal treatment as positive or not. I mean, the fucking KKK assholes think their own direction of unequal treatment is positive and that they’re “protecting their race” which should at least get you started on thinking on just how “logical” it is to keep the classication going and just trying to switch which groups are deemed worthy. The point being that keeping the framework of classification on innate characteristics around and just switching the groups you think good of an those you think badly off, is just changing who is doing the moral judging, not stopping people from being unfairly treated due to the moral judging of others - it moves the unfairness around rather than stop it.
So far, whilst seemingly trying to defend a deeply and very emotionally held interpretation of the world (which is seen as core to the identity of those who feel themselves as members of a specific cultural tribes in your quite culturally backwards corner of the world) you’ve been firing every other way trying to find a logical foothold to justify your own emotional bond to that highly political (over there) take, and all you’ve succeed in is getting ever more illogical - for example, when you say that I “bizarrely am against celebrating what makes people unique contributes to all the beautiful art and expression we see world wide” you’re making such an illogical broad demand that it would mean that I should celebrate “crushing poverty” and “a preference for Coca-Cola over Pepsi” because some people who had a past with both grew up to produce “beautiful art and expression”. The reason for the ridiculous nature of that little jewel of yours is that it relies on an Association Falacy (a kind of logical falacy which, funnilly enough, is quite commonly used by far right nutters, for example one of their “pearls” is basically “all immigrants are dangerous because some murders are immigrants”).
I celebrate the actual “beautiful art and expression” and if certain elements of the past experience of an artist are integral in making it happen, then as I see it they are relevant and it makes sense to mention them (i.e. I’m not against mentioning the sexual orientation of the artist when that helps explain her or his art because that information is entirelly relevant in that context). However it makes no sense to celebrate specific things about people just because of they are part of the life experience that contribute to the uniqueness of some artist, somewhere, and hopefully my example of there being artists whose past of “crushing poverty” and “a preference for Coca-Cola over Pepsi” “contributed to make them unique” makes crystal clear why what you wrote there is a senseless and incredibly vague association.
You are however right that I am triggered: it’s sad and infuriating when I see somebody who deep down probably shares a similar yearning for a more Equal World as I have, doggedly defend with the level of rationality of a cultist, a take on it cloned from the slogans of some political tribe in a culturally backwards country which have long drifted away from rationality (no doubt corrupted by the local politicians) and be incapable of using rationality to reach their own conclusion from first principles or at least pull themselves out a little from their narrow cultural environment and look at things from a fresh perspective.
My expectation of such capability in random people on the internet is indeed highly irrational of me.
