Carano was saying that Republicans are being targeted simply for being Republican and that they are being treated like the Jews. That is not remotely the case. Especially when her post basically said "Germans didn't hate Jews until the Nazis came along, then they were brainwashed into going along with it." Anti-Semitism was rife within Germany well before Hitler rose to power, and he basically rode the wave that was already there and tapped into it. So when you ask, "how could so many people go along with it?", it's because it went along with the feelings they already had. Republicans are not being targeted in this manner, made to wear a badge that says what their beliefs are, stripped of their status and rights, and rounded up as dissidents and people to be exterminated. When people are being "targeted", they're being asked to be held accountable for their actions, especially if it's for fomenting hate, especially the Capitol insurrection, like Carano expressed sympathy for.
Pascal was saying that migrant children at the border being detained in camps was tantamount to when the Nazis would send their victims to the same. I personally would've said like the Trail of Tears and how the Cherokee Nation was treated, myself personally. It is very apt; and pointing out the way that Trump was courting fascism in America is something that many political observers and historians have actually observed and pointed out; this is a bipartisan truth that does not know political boundaries. Pascal was not saying "this why Democrats rule" or actively jockeying for that, he was just making an observation and letting the situation speak for itself, unlike Carano. The context between Pascal and Carano's statements is starkly different.
Besides, Carano's statement was very akin to the Roseanne situation; she charged into a minefield and did not know when to stop. She could've easily gotten away with the Twitter pronouns episode if she'd stayed quiet, but she had to follow it up with the Nazis statement, retweeting anti-Semitic images, mocking COVID protocols, and retweeting "the Clintons murdered Epstein" conspiracy theories. She flouted advice and kept poking the bear; any other employer would've done the same. Carano's situation is nothing like Pascal's statement, just like how Roseanne's comments and firing was nothing like James Gunn being unfairly canned.
And Disney should certainly move to be nonpartisan, however it has a hard time making that stick; not for leaning too far to the left, as has commonly been alleged, but the opposite. 51 percent of Disney's political donations go to Republicans, namely anti-abortion candidates; or at least they did until after January 6.
