Nie cierpię ludzi, którzy tak mówią.

English Translation

I hate people who say that.

“I cannot stand” seems better if to account for the negation.

I disagree. The Polish uses a direct negation with the word nie more often than the English does with the not: double negation in Polish, English no, using antonyms more often in English. Also note Polish Nienawidzę ludzi, has a much stronger emotional charge than the English *I hate people *.
