Classism
Classism is the bias against, discrimination against or dislike of an individual or group due to their social class.
As with other forms of discrimination, such as the various forms of racism, classism is pervasive in leftist and liberal thought. Many supporters of populist political movements, such as Brexit and Donald Trump's MAGA campaign, have faced abuse due to many having working-class and rural backgrounds and are often stereotyped using classist lines.
In liberals
In reaction the election of Donald Trump in November 2016, many liberals used classist lines to attack Trump's core supporters. Elitist musician Billie Joe Armstrong of 'punk' band Green Day blamed the election of the conservative US president on the 'uneducated white working-class'.[1]
On January 29, 2020, RINO political strategist Rick Wilson mocked Trump supporters on liberal-biased TV channel CNN by using the term 'Boomer rubes' ('rube' is a classist term that stereotypes people from rural backgrounds as stupid and backwards) and saying "Donald Trump's the smart one, and y'all elitists are dumb" in a mocking Southern Drawl. Host Don Lemon evidently found these classist remarks funny as he doubled down in laughter on live TV.[2]
