It's weird that the images don't reflect the words at all. Like not even a little bit. 'Oblique' is in Bold instead of Oblique and Italic is in Light instead of Italic. Humanist doesn't mean all caps condensed.
Oblique typefaces are not necessarily electronically slanted, case in point Helvetica. Good oblique typefaces are also carefully designed. There are also some typefaces are are mislabeled Italic when they're really oblique. Italic typefaces require the entire alphabet to fit into a more cursive structure, not just the "a", "f", and the ampersand.
Humanist typefaces are not necessarily more "emotional" in nature, they simply follow a more calligraphic structure. Humanist typefaces can be as emotional or boring as one makes it. Context also plays a large part of course. Seeing Futura (Geometric) or any old Grotesque face typically makes much more excited than Verdana or Lucida Sans.
