Racism can be discrimination by any one race against any other race, so yes, white people can experience racism and racism against white people should not be dismissed, and neither should racism against black people be dismissed because that exists too. It's possible for Indians to be racist against Chines or Japanese, or vice versa. The point is that racism does exist, just like sexism and homophobia also exists, and in a very wide of forms.
