Question

Anti-Japanese hysteria on the West Coast was caused, in part, by racism and fear.

Answer 1

The answer is true, it was during the time Pearl Harbor was bombed 

Answer 2

Any time there's mass hysteria against a particular ethnic, racial, or religious group, it's a result of racism and fear. In the 1930's Hitler drummed up German racism against Jews and stoked fears that the Jews had too much economic power. In Rwanda in the early 1990s, the Hutus and Tutsis did the same to one another. Even today there's immense racism and fear in the U.S. against Moslems and even Hispanics, most of which is being stirred up by politicians and other prominent leaders. This kind of hysteria is never grounded in reason; it's always the result of racism and fear. So your anser is 100% true.
