Should the Natives have been forced into assimilation, explain?

 Many American leaders in the 1870s and 1880s thought that Indians should be encouraged or even forced to assimilate.  That means they wanted Indians to leave their tribes and ways of life, and instead adopt American ways of life.  

  (Assimilation means to blend into a different culture.)

Explanation:

i confess that there are several parts of this constitution which i do not at present approve, but i am not sure i shall never approve them: for having lived long, i have experienced many instances of being obliged by better information or fuller consideration, to change opinions even on important subjects, which i once thought right, but found to be otherwise. it is therefore that the older i grow, the more apt i am to doubt my own judgment, and to pay more respect to the judgment of others.
