Those emigrating to America for freedom, opportunity and a chance at a better life should, as Teddy Roosevelt said, come to America with the idea of grafting themselves into the American tree and fully becoming Americans:
In the first place, we should insist that if the immigrant who comes here in good faith becomes an American and assimilates himself to us, he shall be treated on an exact equality with everyone else, for it is an outrage to discriminate against any such man because of creed, or birthplace, or origin. But this is predicated upon the person’s becoming in every facet an American, and nothing but an American…There can be no divided allegiance here. Any man who says he is an American, but something else also, isn’t an American at all. We have room for but one flag, the American flag… We have room for but one language here, and that is the English language… and we have room for but one sole loyalty and that is a loyalty to the American people.
It is not ‘tolerance’ or a celebration of ‘diversity’ to allow groups of immigrants to remain festering in unassimilated enclaves, cut off from the larger society, clinging to their native tongues and the traditions, ways, ethics, and jurisprudence of the country they emigrated from.
Rather, it is a recipe for and tacit approval of the balkinization of society, which leads to conflicts, violence, and further divisions between people.
