Actually, "hate" is a very strong word. 嫌い is more like "dislike". "Hate" might be more like 大嫌い (dai-kirai = abhor), 我慢できない (gaman dekinai = cannot stand), 憎い・憎たらしい (nikui/nikutarashii = resent/resentful). あなたなんか大嫌い！(Anata nanka dai-kirai!) 君が憎い。(Kimi-ga nikui.) お前のことが我慢できない。(Omae-no-koto-ga gaman dekinai.) Note: Anata = you (polite) Kimi = you (referring to the person equal or below your rank) Omae = you (not very polite, can be used among close friends)

If it's translated literally, it should be わたしはあなたが嫌いです。(watashi wa anata ga kirai desu.) "嫌い(kirai)" means "hate"
