I thought she was Iranian. I do not recall ever hearing her described as anything else.
I think Roseanne’s tweet was bizarre and seemed to come out of nowhere, although I admit I know nothing about its context. But it wasn’t racist. Iranians are Caucasians...
Roseanne strikes me as someone who could change her stance at any moment. I’m not going to champion a loose cannon.
(I wonder sometimes which is more important here: Truth or Agendas...)
