Correct me if I misinterpreted what you've written, but if you think removing diversity is what the "silent majority" wants, boy, are you living in a delusion. You might be trying to make up explanations to forcibly rationalize bigotry. Ethnic and religious diversity is not something you can just turn into "homogeneity" without large-scale genocide. Besides it was never a significant factor in Japan and China's growth relative to India.
