Whenever they want to paint someone in a good light and have you sympathize with them they use weird ass angles with the camera below them tilted upward.

It's a filmmaking technique called low angle. It makes them look taller and thus more powerful, in control, confident, etc. The opposite is high angle and it's used to make a character look small, weak, vulnerable, and not in control of the outcome.

It needs to be paired with some context since it can have different meanings depending on that though. Just look at the opening scene of FOTR, where Sauron enters the battle. The humans are shown as being very weak by comparison, and Sauron is shown as this huge imposing figure through use of these angles.

Whereas in the context of this picture it's meant to make you think that the woman is strong for standing up to Trump, that she's important, that she isn't desperately lashing out, etc.
