It’s clearly an animated mode of a eigen value analysis. Therefore it’s “displacements” that a structure experience when subject to a vibration at it’s natural frequency.

The thing is that these populist politicians are do not have most of the views they are communicating. Many of them might even have very liberal and modern world views. However, the main goal for them is to gain as much power for themselves and their cronies. To achieve that they simply say what their supporters want to hear. The statements of populist are not the statements they believe in, they are the direct reflection of their supporters beliefs.
