Yes. Where are the Rabbanan blamed in Gemarah?
The whole “The second Bais Hamikdash was destroyed due to Sinas Chinam” bit.
Listen, I don’t like the idea of this book either. You could also say (which the Gemorah says as well) that it is the fault of the Rabbonan who didn’t kill Bar Kamtza when they realized he was out to get them. However, if you do want to dismiss it (which I assume you do), the best way is to ignore it, not have an 11+ page thread on it. Who cares if it is the truth or not?
