Wrestling has long had a challenge related to diversity (race and gender issues especially), though the US wrestling community is largely in denial about it or prefers to change the subject.
Look at one of replies above in particular. Or look at the vitriolic anger directed toward Title IX.
The US wrestling community is extremely white, rural, Republican, religious, and conservative, and doesn't like to think or talk about systemic, institutional, or cultural issues.
It also largely doesn't have the capacity (history, resources, curiosity) to do so. It tends to prefer the status quo and to side with authority and authoritarians.
It tends to flee from matters related to religion, politics, and race even though these subjects are intimately connected with athletics, global competition, the media, and many related topics.
This is absolutely incontestable.
Other sports have tried to engage the matter: basketball, football, boxing, among many additional ones.
When the issue arose with a kid having his haircut before a match, most of the major wrestling sites (e.g., FLO) ignored it. The vast majority of the wrestling community became very defensive.
When Jordan Borroughs posted an article related to wrestling and Black History, the wrestling forums ignored it.
These examples can be easily multiplied.
To folks who live in urban areas or who have moved from very conservative communities to more diverse regions, most of the above points are likely pretty obvious.
Indeed, one of the reasons why amateur wrestling is threatened as a sport is because so many of the supporters are loathe to embrace change or constructive criticism or critique.
