A main example of prejudice is Antonio's anti-Semitism. He may borrow money from the Jewish Shylock, but he dislikes the moneylender simply because he is Jewish.
Shylock has not forgotten how Antonio treated him. When Antonio shows up for a loan, Shylock reminds him that he spat [voided his rheum] on his beard and kicked him as if he were a dog. He asks Antonio why a "dog" should have money to lend:
You, that did void your rheum upon my beard
And foot me as you spurn a stranger cur
Over your threshold! Moneys is your suit.
What should I say to you? Should I not say,
“Hath a dog money? Is it possible
A cur can lend three thousand ducats?”
Antonio's cruel and contemptuous behavior has raised Shylock's ire. Rather than apologize when he asks for money, Antonio instead adds fuel to the fire when he asserts he will likely continue the abusive behavior, saying:
I am as like to call thee so again,
To spet on thee again, to spurn thee too.
If thou wilt lend this money, lend it not
As to thy friends, for when did friendship take
A breed for barren metal of his friend?
But lend it rather to thine enemy . . .
It is clear that Antonio brings his problems on himself, goading Shylock with his hateful speech to demand a pound of flesh and to revel in the idea of cutting it out of Antonio's heart when his enemy can't repay the loan.
Shylock also avows prejudice against Christians and is heartsick when his daughter, Jessica
, elopes with a one.
