We learn much about a man by observing the company he keeps.

Over last weekend, Jeremy Corbyn attended a Passover celebration in Islington organised by Jewdas, a near-anarchist organisation described, with eloquent restraint, by The Jewish Chronicle as “a Jewish diaspora group known for its far left anti-Zionism.” Among their more socially-acceptable activities was the organisation of an anti-fascist Yom Kippur ball.

In May 2015, Jewdas took more than thirty people on its inaugural Birthwrong – the satirical mockery of the traditional Jewish doctrine of birthright – trip to Andalusia. This was advertised as “a trip for anyone who’s sick of Israel’s stranglehold on Jewish culture and wants to get away on a raucous holiday. See Maimonides! Get pissed! Do some Jewish tourism! Spend Shabbat with Andalusian Jews! Shvitz in a hammam! Visit a communist village! Get pissed!”

In other words, last weekend’s gathering was one at which Jeremy Corbyn would have felt entirely at home.

Jewdas members have a favourite party game in which a cheerleader calls out names of prominent British Jews and everyone boos. They have a particular dislike for Stephen Pollard, editor of The Jewish Chronicle whom they regularly abuse as “a non-Jew.”

They frequently preach the destruction of Israel: “Israel is a steaming pile of sewage which needs to be disposed of.”

Hearing those words must have greatly cheered Mr Corbyn, the avowed friend of the terrorist organisations Hamas and Hezbollah.

I’m left with just one thought: I wish I could get through to the snowflake, airhead youngsters who are so beguiled by “Jeremy” that they intend to make him prime minister.

I have found much to dislike about many politicians over the years, but I would never have described any one of these as evil – until Corbyn emerged out of his very own steaming pile of sewage.
