I cannot think of an example of a claim that does not exclude it’s negation. If the claim is “X is better than Y” then the exclusion is “Y is better than X.” So to claim it is better to think all people are equal is to claim those who think otherwise are making not-better claims. Thus the confusion of ‘all people are equal except those who say all are not equal.’
You’re assuming that having lower-value beliefs lowers the value of the person holding that belief, which is negated by the claim “all people are of equal value”.
