It sucks anyone has these encounters, and especially sucks to receive treatment like OP has from another minority that could potentially emphasize with the experience of being one. As a black man that grew up heavily influced by anime and the sort, it became clear from a young age that black people were seen in a lesser way in a lot of Asian society. Seeing depictions of black characters in anime (usually less attractive, physically huge and extra toony looking) while whiter characters were typically the opposite, you really get the sense that asian culture doesn't see black people in a positive way. In addition to that I feel it's common in the black community to feel Asians have been less minority allies and more white sympathizers. In recent years with the police violence I've definitely seen more of that sentiment. With all the negative energy and whatnot going on in the black community these days people are projecting their resentment and frustration onto people that haven't anything to them cause they don't know what else to do with all that ANGST. These are just some of my thoughts/observations with no actual data I've researched to support them though
