Fair. You are old though, not just white.
(I've never used Air BnB so don't know what can be gleaned from profiles. Also, obvs all these types of discrimination are shit.)
Older black men are less likely to be stopped and searched than young black men. But the reason young black men are being disproportionately stopped and searched isn't ageism.
I've never been refused an Air BnB reservation, but my name's Mark not Adewale...
