Yes, it is. This focuses on all kinds of people, not just Asian Americans.
The author works with Asian Americans and other populations. This is relevant to the "Deaf" and hard of hearing populations too. Why do we always worry about "Political Correctness"? I work with a Hispanic student whose nickname is Gordo. I have heard his teachers calling him Gordo because it is how his peers called him. His name is not Gordo. I do wonder if any of them knew what it actually means. He even admitted to me that he wish to be called by his real name sometimes.
I am not interested in policing what everyone does, but I believe that it is our responsibilities to tell others how we want to be treated and pointed out those obvious mircoaggrsesions. I don't want anyone to describe me as a "Deaf and Dumb."
What do you think mircoaggressions look like? How can people who commit mircoaggggrsions be so unaware of their actions? Even if they represent unintentional slights and insults? What types of psychological implact do you think they hav eon marginalized groups? Mircoaggressions can be used as racism, sexism, hetero-sexism, etc.
Like the Hispanic student I work with, people called him Gordo as they thought it was his name, but they didn't realize they encourages mircaggressions. They called him "Fat and ugly" in Spanish intentionally or unintentionally.
If you want all reliable sources, I can list them all for you. That class I took, Culturally Diverse Theory adn Practice really opened my eyes. They don't focus on the population of asians, but as well others. Immigrants, refugees, sexual minorities, Jewish Americans, Arab Americans, (ethnic populations), older adults clients, people with disabilities, and gender, racial, and sexual orientation. All of that in one textbook that talk about mircoaggressions, mircoinsults, marcoaggresions, and others.
*Gordo means fat/ugly in Spanish
