This claim comes from a social media platform similar to Twitter, BlueSky, where anybody can post anything. The profile seems to have no professional credentials or verifications. It's just an account where someone posts for pleasure. There is no way to prove or disprove this claim because it is an opinion. DEI stands for diversity, equity, and inclusion. According to Britannica, "Affirmative action in the United States is the active effort to improve employment, educational, and other opportunities for members of groups that have been subjected to discrimination. Criteria for affirmative action include race, disability, gender identity, sexual orientation, ethnic origin, and age." When looking up racism on Google, the definition that pops up is "
prejudice, discrimination, or antagonism by an individual, community, or institution against a person or people on the basis of their membership in a particular racial or ethnic group, typically one that is a minority or marginalized." From these definitions, you can see that they are not all the same things, and DEI is not equal to racism. There is no way to prove this, it is just something that someone thinks with no evidence.
