You've got it nailed. Meghan has a thin skin for legitimate criticism and while she can hurl insults and false stories about others, notably the Cambridges, anyone calling her out for her actions is ghosted or now called a racist/hater. It's the behavior of an spoiled, immature individual that has been doted on and catered to starting from childhood.
Harry has become just as bad. Hence, they're calls for "policing the Internet and social media", it's not so much about others being bullied, as we know, it's about others critical of their behavior and actions.
As an aside, I think Meghan is rattled and nervous as all get out over Samantha's book...she doesn't know what her sister has written and what possibly will be revealed. It's been written in either the Express or Mirror that Tom Sr. has approved of Samantha's book.
