Perhaps, but what's happening to conservatives isn't that, for multiple reasons.
First off, it's not universally about conservatives, or even Republicans. It's about people being dangerous, supporting dangerous and harmful ideas, and blindly supporting those who push these dangerous ideas to the front. And that's the prime difference - these are people actively advocating policies that seek to dehumanize and harm others.
Secondly, this isn't due to a simple random aspect of the circumstances of their birth, but due to choices they consciously made. Nobody is being targeted because of who their parents were. They are being targeted because they themselves chose to do the things they are getting in trouble for.
Third, this is not a permanent and irrevocable situation, nor was it even immediate. If Gina Carano posted an apology and said she didn't realize how stupid what she'd been saying was, she'd probably have gotten a pass on all of this. But this wasn't the first issue, she'd been warned several times what could happen, and she kept posting things that were more and more unacceptable to people. Even now, if she were to come out with a true apology, and show that she really believed she'd done wrong most people would be willing to give her a second chance (although it may take a year or two of her not posting stupid crap before people believed her).
Fourth, there is no dehumanizing being done here. People were told Jews, gays, etc. were less than human. Nobody is saying that these people with extreme conservative views are less than human, just that their actions make them out to be assholes, or at the most extreme saying that they're possibly mentally ill. Neither of which is viewed as subhuman and unworthy of human rights.
