Which sentences in this excerpt from “the destiny of colored americans” by frederick douglass indicate the author's belief that white americans and black americans must unite for mutual benefit? it is idle--worse than idle, ever to think of our expatriation, or removal. the history of the colonization society must extinguish all such speculations. we are rapidly filling up the number of four millions; and all the gold of california combined, would be insufficient to defray the expenses attending our colonization. we are, as laborers, too essential to the interests of our white fellow-countrymen, to make a very grand effort to drive us from this country among probable events. while labor is needed, the laborer cannot fail to be valued; and although passion and prejudice may sometimes vociferate against us, and demand our expulsion, such efforts will only be spasmodic, and can never prevail against the sober second thought of self-interest. we are here, and here we are likely to be. to imagine that we shall ever be eradicated is absurd and ridiculous. we can be remodified, changed, and assimilated, but never extinguished. we repeat, therefore, that we are here; and that this is our country; and the question for the philosophers and statesmen of the land ought to be, what principles should dictate the policy of the action towards us? we shall neither die out, nor be driven out; but shall go with this people, either as a testimony against them, or as an evidence in their favor throughout their generations. we are clearly on their hands, and must remain there forever. all this we say for the benefit of those who hate the negro more than they love their country. in an article, under the caption of "government and its subjects" (published in our last week’s paper), we called attention to the unwise, as well as the unjust policy usually adopted, by our government, towards its colored citizens. we would continue to direct our attention to that policy, and in our humble way, we would remonstrate against it, as fraught with evil to the white man, as well as to his victim. the white man’s happiness cannot be purchased by the black man’s misery. virtue cannot prevail among the white people, by its destruction among the black people, who form a part of the whole community. it is evident that the white and black "must fall or flourish together." in the light of this great truth, laws ought to be enacted, and institutions established--all distinctions, founded on complexion, ought to be repealed, repudiated, and for ever abolished--and every right, privilege, and immunity, now enjoyed by the white man, ought to be as freely granted to the man of color.
