It shouldn't matter, unless the writers are going out of their way to bash you, or jam politics where it doesn't belong. I obviously get annoyed when stupid political jabs are made for no reason, but I don't boycott shows or movies just because of a liberal slant. I think that if conservatives did that, there would be nothing left to watch. Aside from Roseanne, who are the conservatives on TV? Schmidt on New Girl? Are there any others?
And when Christian conservatives are depicted, it's usually as some weird culty figure that dresses like a 1950's sitcom character, while spewing a ton of hatred at people, because they're written by people who have never actually met a conservative.
I was reading a review of Roseanne, and the person reviewing it dinged the show because they couldn't believe that Roseanne not only voted for Trump, but because she expressed no remorse for her decision. They dinged the second episode because they couldn't see how a Trump supporter would possibly stand up for their "gender fluid" grandkid who had to face bullies at school. (and I put the term "gender fluid" in quotes because the reviewer used this label for a character who clearly identified as a boy, not because of any personal views that I have about this transgender issue)
It's insane and it's stupid. I watch a lot of TV, which means that I'm fed a steady diet of liberal ideals and being told how evil I am. The thing is, for a lot of those characters, it makes perfect sense for them to be liberal, so I don't care. Some characters are in no way liberal, but the writers will not call them conservative because it would probably make them sick to do so.
What I liked about Roseanne this week was that the show made fun of everyone. Whereas most comedy has skewed away from actually telling jokes and more toward tearfully preaching to the audience about the evils of conservatism, the show actually told jokes, and they were funny. Hell, I laughed out loud at a Jackie line, despite the fact that she was wearing a pussy hat and a "Nasty Woman" shirt the whole time.
The show was having a real discussion about the grandson who wears girl's clothes, and what that decision will mean for him. It was making gay jokes about Darlene (who isn't gay, but who is played by a lesbian actress). Comedy is funny when its honest, and these discussions were more honest than pretty much anything else I've seen from the teary-eyes dramas over the past decade.
Over the years, I've gone through phases of enjoying Roseanne's show, and thinking that it was disgusting and annoying. I don't know why, but sometimes I'm in the mood and sometimes I'm not. I did make an effort to rewatch some old episodes on Amazon Prime before the revival started, and I can see why people connected to it. TV characters are usually portrayed as upper middle-class families who never wear the same outfits twice, and who walk around with Starbucks cups in their hand as though they have their own personal barista following them around all day. A large, large chunk of the population can't relate to them at all. Roseanne depicted a family who struggled for money, who had to decide between buying shoes for one person or a dress for another, or who had to work two jobs and barely ever saw their spouse. A lot of America relates to those struggles, and a lot of those people voted for Trump.
It seems like every interviewer who sits down with Roseanne to discuss the new show wants her to answer for her Trump-supporting sins. Whereas they will accept a Trump joke from most celebrities, and act as though it is some deep political insight, they want Roseanne to explain foreign relations, healthcare, and union crap.
The media clearly has a bias. Entertainment is made for liberals 99.9% of the time, because the writers live in bubbles where everyone thinks like they do, and they genuinely believe that "most of America" thinks that way. I've long said that writers should have to live wherever their shows are set/filmed, because they way they do it is unrealistic. I have friends who are liberal. I have friends who aren't Christian. In the real world, most people know different types of people, and it's fine. It's just in television and movies that we're expected to follow the liberal propaganda while being told that conservatives are evil at every turn. And Roseanne's numbers prove that this needs to change. Hollywood needs to get out of its bubble and recognize not just the large American audience that they've been ignoring, but the large audience around the world that share similar beliefs.
So I probably could have summed all of that up by simply saying, no. It should not matter, but sometimes it does.
