I think we can push issues towards being less political by reframing them and persuading others to reframe them.
Abortion, gun control, tax rate—these issues are so central to the left-right political divide that they will never be depoliticized.
Climate change is not like them IMO. I think it can be pushed away from the political left-right axis if it can be reframed so that doing something about climate change is no longer seen as supporting left-wing ideas about big government. There is an angle about efficiency, fairness & cutting red tape (carbon tax) and another angle about innovation and industry (e.g. Tesla). I think we should be pushing those very hard.
Beware of unintended consequences, though. The path from “Nice things are written about X on a candidate’s promotional materials” to “Overall, X improved” is a very circuitous one in human politics.
A lot of people in EA seem to assume, without a thorough argument, that direct support for certain political tribes is good for all EA causes. I would like to see some effort put into something like a quasi realistic simulation of human political processes to back up claims like this. (Not that I am demanding specific evidence before I will believe these claims—just that it would be a good idea). Real-world human politicking seems to be full of crucial considerations.
I also feel like when we talk about human political issues, we lack an understanding of, or don’t bother to think about, the causal dynamics behind how politics works in humans. I am specifically talking about things like signalling
