I always wonder whether Harry didn't want the racism issue out there or overblown (because I reckon he made it up/talked up a nothing burger), but Meghan absolutely did, and in this case, they were briefing against each other
That's entirely possible, @RandyRedHumpback, but as was shown Meghan only had to make the incendiary allegation for it to be seized upon by some as if it was written on tablets of stone, only to be made to look foolish by Harry's later comments
Admittedly he could have done that "correction" much sooner, but why spoil 18 months' worth of outrage in his wife's favour while he watched folk attack the institution he detests and hoovered up the prizes for confronting them?
