William O. Douglas,
Knauer v. United States — Opinion of the Court
“ But it is plain that citizenship obtained through naturalization carries with it the privilege of full participation in the affairs of our society, including the right to speak freely, to criticize officials and administrators, and to promote changes in our laws including the very Charter of our Government. Great tolerance and caution are necessary lest good faith exercise of the rights of citizenship be turned against the naturalized citizen and be used to deprive him of the cherished status. ”
