The poem "If We Must Die" by Claude McKay calls for courage and resistance in the face of oppression. The lines that specifically highlight what the speaker wants from his/her audience are:
**Lines 5-8:**
```
If we must die, O let us nobly die,
So that our precious blood may not be shed
In vain; then even the monsters we defy
Shall be constrained to honor us though dead!
```
**Lines 9-12:**
```
O kinsmen! We must meet the common foe!
Though far outnumbered let us show us brave,
And for their thousand blows deal one deathblow!
What though before us lies the open grave?
```
**Lines 13-14:**
```
Like men we’ll face the murderous, cowardly pack,
Pressed to the wall, dying, but fighting back!
```
These lines demonstrate the speaker's call for dignity, bravery, and a resolute stand against their oppressors, urging the audience to fight back even in the face of death.
