It's amazing how "racism" is evident in all races and cultures. Usually, we think of the Black and White issue.
I remember a work associate and I were talking about Japanese, Chinese, Filipino, and Koreans. I mentioned that we were all Asians.
He is Japanese and I am Filipino.
He said, no, YOU are Asian. Japanese are Orientals.
Even amongst Filipinos. I am Visayan and most Filipinos I meet are Ilocano. One elderly Ilocano lady looked at me and said "Are you Ilocano?". I said no I am Visayan. She immediately put on a condescending face while sadly saying "Ohhh....."

One co-worker, upon finding out I am Visayan told me outright: "You're not Filipino....."
I said what am I then?
He said "I dunno, ask Rudy (another co-worker). His wife's Visayan......"
Aieeesoooos. These people. SMH.
