(3) It is claimed that the Chinese are grossly immoral, that they are addicted to the opium habit and other vices, and that so few women come among the Chinese immigrants that Chinese men menace the virtue of white women. (4) The Chinese do not readily assimilate. They keep their language, religion, and customs. They live largely by themselves, and are even more completely isolated from American social life than the negro. In comparison with them, indeed, one is struck with the fact that the negro has our customs, our religion, our language, and, in so far as he has been able to attain them, our moral standards, but this is not the case with the Chinese. It is, moreover, impossible for the Chinese to assume the white man's standards without losing his own social position among members of his own race. (5) The last and strongest argument in favor of the general exclusion of Chinese laborers from this country, however, is the racial argument. The Chinese are just as different in race from us as the negro, and if racial heredity counts for anything it is fatuous to hope to assimilate them to the social type of the whites. Moreover, if we should open our doors to the mass of Chinese laborers China would be able to swamp us with Chinese immigrants. With its hundreds of millions of population China could spare to us several hundred thousand immigrants each year without feeling the loss. If we wish to keep the western third of our country, therefore, a white man's country it would be well not to open the doors to Chinese immigrants. It is certain that if we open our doors to the mass of Chinese immigrants we shall have another racial problem in the West such as we now have in the South with the negro. Those who claim upon the basis of sentiment or humanity that we should open our doors and attempt to civilize and christianize the flood of Chinese who would come to us, probably do not appreciate fully the social status of the Chinese or the social status of the American people. The truth is we are not yet ourselves enough civilized to undertake the work of civilizing and christianizing a very considerable number of people alien to ourselves in race, religion and social ideals. Again, those who advocate the free admission of the Chinese probably do not appreciate the importance of the element of racial heredity in social problems. The negro problem should have taught us by this time that this factor of racial heredity is not to be discounted altogether.
