Jewish Voice for Peace (JVP) have never found a Jewish holiday they couldn’t co-opt to show their hatred of Israel, not to mention their embarrassing ignorance. And they’ve done it yet again (with bonus sexual innuendo!)
Sukkot celebrates the gathering of the harvest (in Israel) and commemorates the miraculous protection G‑d provided for the children of Israel when they left Egypt (to establish their home in the land of Israel). As far as Zionist festivals go, it is right up there.
For the record, it is not the size of one’s etrog that counts, but what you do with it.
