Meghan really does come from the most disgusting low life family.
I can actually understand her wanting to keep them away from Harry and the RF and distance herself from them. There is obviously a lot of very nasty shady stuff going on that's been kept quiet by them.
If she herself came across as a sincere, hardworking, committed, generous personality I am sure there would be lots of sympathy for her having to deal with such low lifes. After all we don't chose our family, and they don't define us.
Unfortunately she has come across herself as a lying backstabbing, self serving narcissist who destroys family relationships and tries to take others down. So the impression when her disgusting family are revealed to the world, is that she isn't that different to them.
