Equal rights and opportunity do not in any way conflict with diversity. Equal rights and opportunity are required to support diversity.
AND
visa versa.
The only way you can facilitate Equal Rights though governing exists in what you don't do to, or for, anyone.
Diversity on the other hand is an attempt to handicap imaginary equality through governance as a means to produce an unachievable result.
In reality ... Equality only exists in applied mathematics or the absence of applied variables ...

Even on a basic molecular level ... You are not equal to yourself for a fraction of a second ... And true diversity is inherent in everything.
.
Your concepts of diversity and equality are silly.
Was Thomas Jefferson mathematically wrong when he asserted that "All men are created equal"?
Perhaps he meant in a political, sociological and legal sense, not a mathematical sense. He did not mean that all men were of equal height and weight.
The way you insure FREEDOM is to insure equal rights and opportunity regardless of the differences between people. That's DIVERSITY!
What they're trying to implement is equal outcome, at least for some, certainly not for themselves since their 'outcome' is already vastly more than the average person. 'They' being the wealthy, those in power and pulling all the strings.
What evidence do you have that anyone is trying to force 'equal outcomes'? We DO NOT have equal opportunity by a long shot, instead we've called 'some opportunity' 'equal opportunity'.
Besides equal opportunity is a whole different discussion.
We're discussing Multiculturalism and diversity, which means that people who are different from the majority of people will not be persecuted.
Evidence? It's all around you, massive redistribution of wealth is the biggest, the normalization of fringe lifestyles into the mainstream, acceptance of students into colleges who have no business being accepted to a university, shoving kids along in the education system that should be failed, potential forgiveness of student loan debt, and the list goes on and on. And you're right, opportunity is not equal, if you're a poor minority, but at least do moderately well in school, you'll have options for all sorts of financial aid assistance to go to college, if you're a middle or even low middle income white student, you better hope your parents are willing to sign on the dotted line in order for you to go to school.
And we're at the point where the majority is now being persecuted in deference to all the fringe minority groups, and it's been institutionalized as well using cancel culture in all its glorious forms. If you're a white conservative, your opinion is not only not wanted, you may pay the price for verbalizing it. And 'different from the majority' is a fallacy in and of itself, everyone is different and unique in their own way, it's the grouping and categorizing that the left loves to promote so they can pitch each against the other to cause hate and division. If you don't see all of this happening, then you're willfully blind.
