It's pretty funny that Westerners are still going on about this largely invented issue after underwriting a brutal genocide in Gaza for almost 18 months. Won't someone please think of the oppressed Muslims!
This seems like quintessential whataboutism. I think expanding on how that concern is "largely invented" would serve your point better. I, at least, would be interested.
It shows up so naturally that one may think it is not whataboutism at work, even though the reasoning is often not well argued. We could choose to see it not as a moral judgement, but as questioning the justification of efforts pushing for conflicts with China.
