The concept of notability is similarly subjective, the issues like the mentioned race/gender identity (or e.g. the Russian-Ukrainian war recently) are perceived as very notable on English Wikipedia.
I admit that it is not perfect. My argument is that Wikipedia at least tries to draw to line. There was a time even for Wikipedia, before the inclusionists vs deletionists conflict, when this was not the case. Unicode is still stuck in this phase and that is what I lament.
