I would add an additional and always overlooked "oppressed class" to the list in the article (of blacks, LGBTQ+, illegal aliens, and man-hating lesbians).
The communists who sold Marxism to American universities and colleges in the 20th century convinced the academic class that they were also part of the oppressed class (being oppressed and subordinated by the ignorant business class).
Academics were prime candidates for inclusion in the "oppressed class" because they were extremely sensitive to the fact that, though they were much smarter than those stupid Americans outside academia, they were financially poor in comparison.
As we can see so clearly now, the academics have taken their revenge on the rest of us.
Thanks. Missed that one, but then there are so many soul sick groups and individuals..
