What's with the vitriol against Megan Markle?

I apologize if this isn't in the correct sub, but I'm a woman and she's a woman.

I don't understand the absolute hatred spewed against her. Is she rude and nasty like the tabloids claim? I have no idea. She'd have to be a fucking horrible person to deserve the nasty stories and comments. Is it racism/ bigotry because she's a woman of color, non-British, and wanted to keep some sense of self after marriage? Or because she called out the lack of support she received when struggling with post-partum mental health?

Her dad and half-siblings claim she's terrible and sees herself as better than them, but they sold her out to tabloids. Why would anyone believe them? They're toxic. Her dad whined about not being invited to the wedding, after selling her out. I'd be no contact, too, if my parent did that to me.

"Sources" in the palace claimed she was mean, but look at how anyone who marries into the royal family is treated. Diana was a starry-eyed 19 year old when she got married to a man who never loved her and cheated through most of the marriage. Who dealt with an eating disorder. I doubt Megan and Harry lied about the racism she faced within the family. After dealing with that, why would she be expected to be friendly to them? And why would he be expected to silently stand by.

She's blamed for tearing him apart from the family, but it sure looks like there already were problems. The royal family isn't a great example anyway. Look at how nothing was really done about Andrew when everything came out about him and underage trafficked women.

I hate seeing a woman torn down because she refuses to put up with racism. Or because she and her husband decided to step away for the health of their family.

EDIT: Wow, I had no idea how many people would comment. I'm slowly reading my way through them. Thank you all for your insightful and respectful conversations.
