One thing I absolutely cannot stand is the assumption that if you’re against the Israeli government, you must also be antisemitic. In many cases, nothing could be further from the truth.
The Israeli government is just as screwed up as any powerful government, and is not immune to criticism. Groundless accusations of antisemitism are often used to unfairly attack critics, distract the listener from valid criticisms, and derail the conversation.
Of course, many of those accusations are completely justified, which clouds the issue further.
