Given the rest of what she has to say in that same sentence, I would agree with her. Her reasoning was that the US Constitution, as written, treats anyone who is not both White and male pretty abysmally.
Now.... That doesn't say that one could not look to our Constitution as amended as a guide, and on that point, I would say that Justice Ginsburg is an embarrassment to not only her profession but to her country.
And I agree. I would not be upset if she simply remained there, especially since her trip was paid for on taxpayer dollars.
