Extremists tend to have anime pfps. Conservatives listen to the radio way more often, and are pretty much the only audience of radio talk shows. Progressives have a tendency to consider the implications of the media they consume way more than conservatives. Liberals tend to play tabletop games more often than other political groups. Socialists (of all variations) are the most likely group to have taken unconventional lifestyle choices (i.e. they're vegan, live in a commune, make their own clothes, etc.). Authoritarians are obsessed with "the natural order". This tends to shine through in the justificationns they give for their political beliefs. Anarchists/Libertarians shy away from the mainstream of literally anything (punk rock is a shining example, as is their prevalence here).
