This might not be a popular idea.
I think to be more inclusive and progressive is too remove ethnicity all together and just be people.
People should not have to be fetishized. Some people do want to do that to themselves and then we wonder why racial statistics do not change. By 2040+ the majority will no longer be as prevalent.

Do not allow user to type in their ethnicity when creating an account, this will lead to more people sending their real pictures instead of some picture they got from the internet, it will also reduce the number of people without profile pictures in the wake of men being targeted on this application and attacked sometimes even killed by discreet users, I also support that all users be verified so that when a crime has been committed this will help the police with investigation.
