Maybe some of the left wingers who use Haley's birth name can comment on their intent?
Are they trying to mock Haley, her heritage and even suggest she's not eligible for the presidency or are they trying to score points on the deplorables who loved using Hussein for Obama (and all sorts of nicknames since Trump).
My impression is that the right wingers used Hussein because they thought that was a landed punch that should cause damage.
My impression is that the left wingers use Nimrata because they think that the MAGA/right wingers think that it's a landed punch that should cause damage, except it's one of their own.
Of course this interpretation means that the both sides aren't exactly the same and that there isn't glaring and obvious hypocrisy, I know that's difficult for some to accept.
This interpretation also gives the benefit of the doubt to the left rather than the right. I'm OK with that given the existence of the deplorables/MAGA and belief that the two sides are not exactly the same and that there are differences.
Just something to consider.
