It's a real shame that Meghan bashers/royal stans can't go two minutes without making personal attacks on other posters.
There were many newspaper stories and headlines at the time, accusing Diana of bullying. Nearly word for word the same as the tabloid stories about Meghan, and Kate had identical stories about driving staff away that did not use the word bullying but instead terms like "behaviour" and "demanding" or "refusal to respect protocol."
It's reasonable to point out the transparent tactics used by Meghan bashers (a well-organised group who have engaged in horrific tactics, such as running hate and harassment campaigns against any charity the Sussexes support, and directing targeted harassment against individuals, for example the recent Twitter campaign to contact the university administration to try to get a young girl kicked out her university course, for having the same name as the obviously much older person who started the PrinceOfPegging hashtag).
Claiming to have never heard of anything that might remotely put the RF in a negative light (no matter how well known or well reported) is a very common tactic, and clearly done with the agenda of implying that anyone mentioning it as a liar.
This tactic is always followed up with ever-more aggressive demands for proof (funnily enough Meghan bashers never provide proof for their outlandish claims, they simply vanish then name change), yet I can tell you exactly what happens if anyone does attempt to provide proof:
a: Sneery belittling putdowns along the lines of, "Oh a tabloid! I thought Jemima meant real proof, poor Jemima must be very stupid and gullible!"
b) Attempts to paint the other person as obsessive, "OMG you actually went and dug up old newspaper articles from 1992 giggle giggle patronising head tilt. What a weird, obsessive thing to do!"
It's incredibly manipulative.
Last year I pointed out that a poster had once used a particular racial slur (in a thread full of people saying "I've NEVER seen racism against Meghan, I don't remember any racism against her at al" - the old "WELL I'VE NEVER HEARD OF IT" tactic for the millionth time), which generated pages of rants about what an evil horrible liar I was and how dare I accuse someone. I posted a screencap of the post where the poster in question had used the racial slur. Did even one person admit I was right and had been proven right? Did even one person apologise for falsely calling me a liar? Did even one person express disapproval towards the poster who'd used a racial slur? Of course not! Just pages of "OMG Jemima actually screencapped someone's post, what a stalkerish thing to do, I am genuinely frightened of Jemima she's obviously unhinged and obsessive."
Tactics. Just tactics.
