I can understand if your right wing position comes in the form of fiscal policy but right wing social idelogy goes against the absolute spirit of Trek and most sci fi these days, Supergirl included.
I don't believe that's true so much either. But it's hard to counter without you giving an example--though for sake of this thread and not derailing it, could you provide a Supergirl example of a conservative value that goes against Supergirl? If something comes up organically in a Star Trek thread I'm participating in, I would be happy to discuss that as well.
You missed the

I see. Though conservatives politicians speak enough in front of cameras showing us who and what they are, we don't need hollywood for that.
You have to understand, that while I did know you were joking, the writers don't seem to see it that way. It's very frustrating to constantly see conservative values demonized by Hollywood, who clearly have no clue what conservative values are. The only show in recent times that skewed liberal but didn't completely demonize conservatives was The Good Wife, and I didn't complain then because that was the type of show it was. Plus, the conservative characters were not treated terribly.
Now if you do believe that about conservative politicians, then does that mean you agree that maybe a superhero show should just be a superhero show? As a conservative, all I would have liked was maybe 2 or 3 lines changed to NOT demonize half the country.
Maybe in the early years of the character but I don't see Superman being a big fan of current Conservatism. Supergirl is a strong empowered woman who fights injustice, corruption and in this show has a gay sister...It's a show for an audience with a clear progressive view on social issues, which some people on the right can fall into (some).
I'm going to guess that you may not see Superman as a fan of Hollywood portrayal of conservative views, but I see him as a true fan of actual conservative views. The character is my favorite comic book character of all time. I guess it's a function of who writes him, but the character that became so popular is the one that in my opinion, would be a conservative. And for what it's worth, I really liked Superman when he appeared on Supergirl.
Just to address Supergirl and what you said specifically, conservatives have no problem with strong empowered women. Why would we? They're kind of awesome. Fighting injustice? We're all for that too.
A gay sister? I know this may come as a shock, but acceptance of gays and gay rights, including gay marriage is NOT liberal only thing. Now I do disagree with how the show ran the Alex storyline this year. Again, it's a superhero show, and I think they spent way too much time on the romantic subplot of Alex (a feeling I would also have if she were straight and Maggie was a human male cop), but that's another issue.
Yes, the show does have a liberal slant. I do admit that. But that doesn't mean it should overtly shill for the democrat party and demonize Trump the way they did last night.
I really enjoy this show--and all of the DC shows. A lot.
But last night went way over the line, and I feel that it's very fair to call them out on it.
So, don't watch the show, problem solved.
Another way to solve the problem is to keep politics and shilling for one party off a superhero show and NOT alienate half the country.
Your solution is not very tolerant.
If you liked that Cat speech, that used to happen thrice an hour on Ally McBeal.
Boston Legal was worse, though that was a David E. Kelley staple. I only watched Boston Legal because Shatner was so good on it. Then I realized that if you fast forward Alan Shore's soap box rants, the show got a lot better if you weren't uber liberal.
