There should be a race filter /ethnicity filter. It may lead to many profiles being missed out on just because ppl may not fill up this information in their profiles settings. That may be a downside. Mixed ethnicity profiles and no race / ethnicity profiles shud by default appear in all race searches.
This is not hateful or racist.this is just convenient. One may want to have a black season followed by a white season and vice versa. This is not hateful. A real racist would anyways not want to seek another race they are biased against. and in a way thats also a good thing cuz eg why would i want to be available on the grindrr grid to a bunch of hateful racists who may end up hurting me . The filter does not promote hate or resolve hate
