I see plenty of east asian and african descent folks when I go to the range and have always felt the more the better. Hopefully you feel welcome at any OSA events that happen.Hard to say since I mostly stay in the OKC metro and this place is as cosmopolitan as any other major city now.
But a few years back I did go to the Friends of NRA event at the Cleveland County fairgrounds and I stuck out like a sore thumb LOL. Nobody was mean to me or anything but I could tell a lot of people were surprised to see me in the crowd.
