I'll talk with respect to India. A bunch of dominant caste (including a decent chunk of middle caste and uplifted/politically represented lower castes) folks rent houses, of which, the upper castes are simply the worst kind of landlords.

A small minority of them don't discriminate, or disregard this, when money is involved. But most still do.

How exactly? They ask for your full government name - your surname speaks about your caste. But that would be really rude in the 21st century, right? How exactly do they mask casteism then?

Convey your caste using a lifestyle - "Oh, sorry, we don't allow non-vegetarians". This was literally our personal experience, especially in Mysuru, for the first time in my life. I was left stunned. And mind you, these people are educated, and have great jobs in the public sector.

In the Hindi-speaking belt, they are even more direct about their bigotry: "We only allow people who come from अच्छे घराने (acche gharane, meaning good families)". But you already know who the good, well-mannered families are, don't you?

If I see someone with truck nutz, that person is 100% voting for Trump.

I've always felt like conservative people are more likely the type of people who walk their dogs off leash. Don't tread on me extends to their pets

Conservatives are more likely to follow college sports, while liberals are more likely to follow professional sports.

Why? Beats me.

Edit: I read this in a study once. Might be this one. Also, I'm reminded that basketball fans are more likely to be liberal as well.

I think that question is hard to answer as there are very few topics of everyday life that aren't at least remotely political.

Big cars, weapons, traditional family models (e.g. stay at home moms), focussing on traditional industries such as petrol than new technology such as solar etc. are all typical conservative topics. I mean conservative already implies with its name that you want to conserve the 'as is'.

Contrarily, progressive and liberal people will be more open to changes and trying new things: food, new ways of transportation, new business models, other family concepts.

Liberal men think they're to good to watch sports then gush over super hero movies

It's hard to say, because it's not the first thing you learn about somebody. If someone's dressed remotely nicely, I can instantly tell they're from the city, and I suspect it's more likely they're a liberal, but I don't really know unless it comes up.

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).
