Irrational hatred for people different from you results in all the undeserved persecution, discrimination, and genocide ever exiting. Look at yourself and your irrational fears and hatreds when you read this poem. Let's begin to critically review these beliefs. Robert Pinsky is the poet laureate of the USA and ocassionally hits the mark. This poem does for sure.
Hatred drives much of what happens, public as well as private.
The Polish poet Wislawa Szymborska comments on hatred in her poem of that title. How easily it vaults the tallest obstacles. How rapidly it pounces, tracks us down. It's not like other feelings. At once both older and younger.
