It is not directly "a conspiracy" but it
is the result of a conscious approach of getting people in educational institutions who are willing to be activists for ideologically "left-wing" causes. This has exploded in the last few years with more and more institutions taking up critical theory as a guideline for their curriculum, leading to demands for "diversity, equity and inclusion" in more and more fields.
If you disagree I'd like you to explain where I am wrong instead of just downvoting this post. Explain it in clear terms, using words which were in use in the 90's, which can be looked up paper copies of dictionaries from that time. This seemingly strange request stems from the recent trend for dictionaries to change the definition of terms to fit a narrative, Merriam-Webster being one of the examples of a dictionary guilty of this transgression.
