I completely agree that seeing Black people traveling internationally in large numbers does help break stereotypes. We were in Tahiti some years ago and some of the locals thought DH was an NBA player. He's 5'10" and had on a Lakers jersey (Bryant 8). DH does not look like Kobe at all and he's not NBA tall but they saw a Black man (only Black man I saw for 3 weeks) and they presumed he was rich and famous. That happened to us in St. Barths, and Bangkok, locals presuming we were famous.
I've heard of that happening in this country too. A couple of coworkers traveled up to Maine for a business trip and several people at the hotel thought the black guys were basketball players - not a single one of those dudes was over 6'0".
