I don't get how it is insulting
While yes, the issue of mental health affects all walks of society, Harry and the Cambridges have all taken a different approach to mental health. Harry focusses on soldiers and the impact mental health has on them. William focusses on bereavement. Kate's focus is a little less clear, seems to be mainly children. For Meghan to focus on women's mental health would be her angle in joining the work that the trio already does. It would only add to their work, not take away from it.
No one suggested Meghan was the ONLY voice for women. Simply that she could be a voice for women. There are many causes that affect women in society, and room enough for more then one royal woman to speak on.
For no other reason then what you say right now, I hope Meghan declares herself a feminist, AGAIN.
This sick need for anyone, especially other women to paint feminists as RABID is embarrassing. Women who want equal rights to men but who cant be bothered to speak up for themselves. Painting other women as man haters. Feminists do not want special rights, they don't hate men, they want equal rights. Maybe if other women stopped attacking feminists, while enjoying the freedoms those feminists earned them, maybe we wouldn't be tarred and feathered constantly.
Its great men like Justin Trudeau have stepped up and shown feminism is not an evil world. Nor is it something only women are.
Of course anytime a woman doesn't sit demurely and quietly, and ask for a petition over tea, she is rabid.
