Personally, I don't feel white guilt even though the colour of my skin is white. I am half Caucasian and half Japanese so I identify as a person of colour because the first thing people notice about me in western culture is my Asianness. I think what does make me feel guilty, though, is the fact that I participate more in activism for racism against Asian people, especially during the pandemic. However, in reflecting upon these issues I notice that my Japanese parent does hold implicit bias and does not think that the racism black people experience is as bad as the racism he experienced. Within the Asian community, there are racist overtones coming from the (Very large) majority white-skinned population which has not yet been solved as they are not used to a multicultural setting as they have not grown up with it.
Personally, I believe that there should 100% be solidarity between all POC as we all experience racism based on our appearance, however, this should not by any means diminish the struggles that black people have and are experiencing.
