The first is the longer of the two. It's full of 3+ syllable words, and perhaps will require more than one reading. (It reads more naturally in its original context.)
This is Melanie Phillips' reference to
the foaming fury amongst the Israel-bashers, whose edifice of lies is maintained by casting critics who dare to call this by its proper name as a supremely manipulative lobby merely peddling their own paranoid propaganda -- and whose nefarious power is supposedly proved in turn by their very protests.
In other words, it's a reference to the well-practiced technique, utilized by Israel's opponents, of trying to stifle debate by accusing others of stifling debate.
The process is all too common: It begins with a statement or column or book that lies about or unfairly demonizes or delegitimizes Israel. People express that this statement lies about Israel (or perhaps that the book demonizes... or whatever other combination of the above you'd prefer). Inevitably, Israel's most dogmatic critics scream out against the lobby that tries to squash criticism. How dare they try to squash criticism!? How dare they speak out?! How dare they speak??
Oh wait... who's trying to muzzle whom?
Statement number two is shorter. There are no 3 syllable words. It's more funny than it is piercing. But then, maybe it's equally piercing. Tia, a reader from the West Coast (Jewish Voice for Peace's home turf) brings to my attention this pithy statement, used to describe JVPers:
Proud to be ashamed to be Jewish.
Perfect. Just perfect.
