>I fear you think that this issue is in some way political.

You are the one who started out the thread by suggesting that it's somehow weird that white people don't use white skin-tone emojis, while also arguing that "yellow-as-default" is somehow problematic and/or insincere.

Those are both plainly political. Identity politics, and racial politics, are politics. You are implying that people should change their real-world behaviour for reasons related to race.
