As for this whole topic in general, I love the character of Cara Dune - a refuge from Alderaan having to find purpose again in the aftermath of the war - and I think a recast is best. I wondered if it’s possible for Lucasfilm to have fired Gina and told her, ‘If you stop sharing offensive stuff for good we’ll consider re-employing you’, but honestly I don’t think the relationship between her and the cast and crew (particularly Pedro, who is staunchly anti-Trump) would ever be the same again. There are plenty of other actors who would love to take on the role.
I think its a stretch to say that Pedro Pascal would have had problems with Gina. People with different political views work together all the time. Just look at Richard Donner and Mel Gibson. Their worldviews are like, diametrically opposed and they still managed to make six films together and seem to be on good terms to this day.
