You: White people are 79% of the publishing industry. Do you oppose diminishing White Supremacy (I mean, they're way overrepresented!)? Are you saying it's okay?

White Supremacists: Jewish people are 2% of the american population, but they hold the majority of top positions in the publishing industry. Do you oppose diminishing Jewish Supremacy? Are you saying it's okay?

Both of these arguments are terrible, and are both based on the premise that over-representation of some group in some industry or position constitutes a serious problem and probable conspiracy.
