The UK Labour Party's flirtation with anti-Semitism has become much more concrete under the growing power of the left. And now there appear to be numbers to back up that larger trend.
Anti-Semitic hate incidents jumped in the first half of this year as the Jewish community was targeted three times every day, figures have revealed.
The Community Security Trust (CST), a charity which monitors anti-Semitism, recorded 557 hate incidents in the UK between the start of January and the end of June.
This was an 11% increase compared to the same period last year, and the second-highest total for the first six months of a year since the organisation began compiling the data in 1984.
Some UK media has tried to spin it by blaming it, and everything else on Brexit, but the numbers don't add up.
There was no "obvious single cause" for the high monthly totals, the report said. The CST did not record a significant increase in anti-Semitic incidents immediately after the EU referendum.
So what's left? It's red and ugly.
April, May and June "did see sustained public debate about anti-Semitism, particularly in relation to the Labour Party, and about racism and extremism more generally", the report added.
And any discussion on the subject of anti-Semitism on the left tends to only produce more anti-Semitism from the left.
