In the article you linked, the section on antisemitism is mostly about the Anti-Defamation League's (ADL) criticism of HRW. The ADL itself is not exactly unbiased - it's primarily a pro-Israeli lobby group nowadays. HRW is usually criticized for being too closely aligned with American foreign policy. The Israeli-Palestinian conflict is a notable exception, and HRW's criticism of Israel's treatment of the Palestinians rankles a lot of supporters of Israel.
