It's envy. If envy is foreign to you, It can be difficult to imagine just how intense of an emotion envy can be for most people. Look at what the political correct complain about. White beauty standards, slim women, big breasted women, competent and confident men... they basically complain about anything that could make you feel envious. It's noticable even in art, as the left very much prefers art that has no technical skill and thus cannot inspire awe or provoke envy. They will absolutely wreck you just too be relieved of their envy.
