Things fall apart chapter 20-22
How did the two missionaries respond differently to cultural misunderstandings?

The two missionaries responded in the way that one stood his ground while the other thought it to be fruitless to try.

Explanation:

In these chapters of the book, Okonkwo the protagonist of the work and an Igbo chief of some importance had decided that he will oppose the influence of these missionaries over the land he is of.

Thus, his struggle begins against their influence and he is able to say to them that they must leave the village.

One of the missionaries gets scared of by this insistence but the other is able to stand his ground against the insolence he believes it to be and thus he is able to see the wrath of Okonkwo on himself.

the speech this question is referring to is president kennedy's special message to the congress on urgent national needs, may 25, 1961

kennedy responds in a very direct and concrete way to those thinking that communism is a positive system:

"yet their aggression is more often concealed than open. they have fired no missiles; and their troops are seldom seen. they send arms, agitators, aid, technicians and propaganda to every troubled area. but where fighting is required, it is usually done by others--by guerrillas striking at night, by assassins striking alone--assassins who have taken the lives of four thousand civil officers in the last twelve months in vietnam alone--by subversives and saboteurs and insurrectionists, who in some cases control whole areas inside of independent nations." (kennedy)

president kennedy presents communism as cowardly, as a hidden and treacherous weapon that strikes from the shadows like thieves, he represents the system as not even being capable of showing and open and overt attack or confrontation. to finish up the response, he expresses that the system attacks even a country's idependence and freedom.
