No, I simply don't accept that politics is preference. Politics is in some ways the physical manifestations of our values into the world. They affect people in real and profound ways.
A "preference" for the subservience or disenfranchisement of certain people, for example, is no mere preference.
I actually agree with what you wrote, but it’s interesting to note that many fewer people believe in universal values.
Many now believe that values are a preference (this is not something I believe, though, as I believe in objective morality, with the caveat that I realize it’s just a belief, like a belief in angels or something).
