Except the vast majority of people who use "diversity is our strength" as a slogan are focused on superficial "diversity", while ironically still demanding all remain in ideological lockstep; no diversity of that kind tolerated within the 'in-group', that's for sure, lol.
There's much more true, pragmatically 'useful' diversity in, for example, a group of ten white males whose values and views cross the political etc. spectrums, than in a group of ten people of all different races, half male half female, who all have the exact same political views and values as each other.
The Olympics is about 'blindly' rewarding the best of the best, regardless of those superficial characteristics, so the "diversity is our strength" ideologues don't get to 'claim' it, its premise directly contradicts those people's values--they'd rather a job position be filled by someone who meets a sex or race quota, than simply hiring whoever is best for the job, etc.
