True
Step-by-step explanation:
In this poem, Rudyard Kipling refers to his difficulty to deal with strangers. By strangers he refers to foreigners in his own land, people within it's borders. This is demonstrated with this phrase: "The Stranger within my gates".
By using the word stock, he refers to some particular values and characteristics shared between the people he sees as his equals. As he refers to a geographic or political delimitated area, we can infer people share some racial and ethnic features.
