Contextualists miss nothing. Onus is on you to be clearer in your communication. I've asked you to clarify multiple times. Can you link me to the literature that is currently inspiring you. I want to understand, however if you will do me the courtesy of reading back some of your own writing from a different perspective, you will find that you have contradicted yourself a few times and that there are a few terms you use that need to be better defined.
I agree with the sentiment of this, however there is a diversity of modal qualities to every value expressed and clear conflicts of prioritization between values. Security/Freedom is one such conflict. There is also a diversity of thought in meta-ethical dialogical positions and reducing them to something simpler than that, eliminates the subtle but profound impacts of the differences in nuance has on the modal quality of values.
That's the problem we have been addressing. Your reductionism isn't helping. If we cannot discuss diversity and how it relates to equality and equity, then we cannot have the discussion at all. This is about barriers to education. Now, you can express your view, but if you cannot recognize the influence concepts or social constructs and how others view and use them, have on the barriers to equal opportunity in education, then you are ignoring the majority of the problem.
A few facts to keep this all on track.
F1. Not everyone shares your view on how things are, or how they ought to be.
F2. Bigots exist.
F3. Bad faith decisions made by biased individuals on who does or does not get into a certain school, happen.
F4. There are a few different degrees and types of discrimination, direct and indirect, conscious and subconsciously.
F5. Some people believe diversity exists and has value in a number of different areas.
F6. Public discourse does not take these concepts lightly.
Conclusion: It is not pragmatic to take the fringe belief that diversity is the antithesis of equality and claims like that require proof. Especially since the concepts 'Equality and 'Diversity have uses in a multitude of different situations. Here, we are discussing equality of opportunity. Believing in the values of equality and diversity are not mutually exclusive. There is even a way to be pro-life and pro-choice based on pragmatic modalities of the underlying values involved.
