1. Asian guy is mad because of actual shortage of Asian women, then even more shortage because a good deal of em declare their love white guys regardless
2. Asian guy is

when Asian girl is with goofy foreign white guy despite massive surplus of men of her own culture
3. White guy can't fight back because Asians will see a foreign attack their own n instantly jump in. Could jail/deport white guy let alone triads come and eff him up or.....worse
4. Asian guy was prolly drunk and tired of silently judging so he couldn't contain it
5.

feel for Asian guys. Get called weak, seen as non-masculine, barely seen in strong mainstream roles but some of their pop stars look like legit women and they can't really grow full beards.....still tho love is love. Just ignore the girl man
