He definitely was doing that, i agree.Depends on how he asked.
if he was asking to show genuine support of the cause but questions about process for funds that’s fair to address.
the way Musk asked sounded like he was insinuating the UN would just abuse the funds hence the reason he shifted the discussion to accusations about UN officials raping/molesting kids
But i don't think people would get mad if say a leader from BLM tried to get him to donate billions for réparations and he then pointed out accusations against BLM leaders of embezzlement. People would know he's trolling but would probably still side with him because the trolling is backed by what some perceive to be legit accusations/questions.
