Do you have any advice for writing characters I disagree with? I have a character who I think would be politically conservative, and I am not. They're not supposed to be good, but they should be likeable. I keep switching between giving them really bad strawman opinions and just giving them my own views, and none of those are right for the character. It's really difficult to get the nuance right.
I think the key here is thinking about how people end up with the beliefs that they end up with.
Whether it tracks through with facts, belief systems are generally built on some sort of logical infrastructure that would then show up in this character's thinking.
If you take anti-immigrant views, for example, there are a few types of things that you see, often ultimately based on fear and/or anxiety. One of the biggest fears is that immigrants are "stealing" people's jobs. This may be based on the character's own anxieties about economic access or instability, or it's based on having been fed a constant stream of media noise about it, etc. Alternatively, their fears may be about race or religion--about the idea that people with the same cultural, religious, and racial background as them will no longer be the majority. This may manifest in thinking about what "type" of country it is, or about economic or political access, or about fears of oppression by a previously marginalized group.
I'm oversimplifying a bit, but my point is this: people with every viewpoint, whether it's one we agree with or one with think is cartoonishly evil or anything in between, has a foundation to that view. That is how you write someone who believes something different from you: you decide what the foundation is of their beliefs and then you write them from there.
And sometimes you'll write them and hold your nose and say ick ick ick and know it's still the right way to write them because they accurately reflect a point of view that you hate.
(Also I just have to say - the concept of politically conservative, which was always a little complicated, has become extremely complicated in the last decade. Is their conservatism based in fiscal conservatism and being a deficit hawk? Is it based in the Christian right? Is it populist? Is it based primarily in racism? Are they a neo-con war hawk or an isolationist? Do they fall more in "everyone should pull themselves up by their bootstraps" or "we should be bombing abortion clinics"?)
As for making them likeable--you can't make every reader like them, no matter how you write them. But if they're supposed to be likeable to other characters, then that is likely to do more with personality than with beliefs. There are charismatic conservatives, there are kind conservatives, there are generous conservatives--maybe not to everyone, but to the people who they like (and, to be fair, liberals/progressives are not necessarily kind or generous to people they dislike, either).
Someone can have anti-immigrant views and be good with kids. Someone can have fiscally conservative views and be sweet to their husband or wife. Someone can be anti-feminist and help their friend move. Political beliefs don't preclude personal kindness or charisma.
