The problem is that Asians don't have a story of discrimination. Blacks have slavery, Jews have the holocaust, Native Americans have their land being taken from them, and Latinos have being raised in a third world country and fled to America on foot. These are simple, visual stories as to why they were all discriminated against.
But Asians, along with Indians are mostly relatively wealthy immigrants that came here legally. There is no story of their collective hardships, so no heart strings are pulled, so no one cares.
If there was a movie about discrimination and hardship, the Asians would be cut out of it, being their story was too boring and not dramatic enough. That is the real reason.
