The Meghan bashers simply hate her, have always hated her, will always hate her, will always find a way to put the most negative spin on (or outright lie about) anything she does.
You really have no proof that people 'hate' her and certainly none whatsoever that they have always 'hated' her or that she's subject to more 'hatred' than either Kate, or Fergie have received.
In fact after her engagement interview with Harry I roundly defended and praised her (under a different name) and some who now voraciously defend her on MN didn't at first.
People can change their opinions. Demonising everyone who questions H &M while defending them is just as wrong. Neither do I understand the almost frantic desire to cast them in a positive light especially by those who claim to be republicans but then perhaps it does make sense if you are not judging their behaviour against the notion of preservation of royalty but simply in the framework of being ordinary people.
They certainly ought to receive scrutiny. Like it or not they are the ones being vocal about their environmental credentials then doing the opposite. No ones asking them to launch private green washing initiatives or for their opinion on anything at all. They volunteer it. No one is asking them to hop on planes to watch matches you can watch live on TV, they are choosing to do it. Or spend millions on a reburbishment during austerity, or demand privacy while using PR to maximum effect and spend time highlighting the work of private companies.
Yet if you call them out you are 'hating'? What are people meant to do? Just say all those things are great and just concentrate on all the positives?
And Kate did receive some scorn for her Chelsea garden in the form of WTF has she done to merit getting the opportunity to a garden at Chelsea?! Interestly people defended her and looked past the issues in the same way people do constantly here regarding M.
