That's a very rational analysis, but I think a factor that is more relevant to politics is people's strong gut reaction to issues. Some people reflexively oppose all efforts to protect the environment. I'm very liberal, so I have a lot of friends who reflexively support all government regulation of business, without bothering to know the specifics. I would call them anti-business. Or if you tell someone there was a police shooting last night and the first thing they say is "Fucking cops!" instead of "What happened?" then I think you could call them anti-police.

Maybe if you ask them rationally what their opinion is, it will come out pretty balanced, but that standard glosses over a lot of deeply rooted bias.
