Wouldn’t it still look weird because the two images are offset in a different axis than your eyes?

That just shows that one axis is too few to categorize political opinions. The opposite of liberal is authoritarian and while I definitely would say I’m a leftist, I’m not pro authoritarian.

Sadly, “liberal” partys nowadays are mostly economically liberal (i.e. freedom for corporations, deregulation etc.). But you can also be socially liberal, i.e. support individual freedom.

(N.B.: I’m not from the US, maybe the definition of liberalism taught in school here is different, or the literal translation is used differently)

I don’t use GNOME, but from what I’ve read (and from experience with other software that has extensions) they often break when GNOME updates.
