You can acknowledge that Peter Mandelson may not identify as a Jew because only his dad was Jewish, and that other people who have Jewish dads do identify as patrilineal Jews - and also recognise it isn& #39;t appropriate to make comments about "counting gold" about either...

Also: If you don& #39;t identify as Jewish, don& #39;t start commenting on the legitimacy of patrilineal Jews

It is a very painful topic for people who identify as patrilineal Jews and shouldn& #39;t be casually debated in order to defend Len McCluskey& #39;s comments about Mandelson

And if you are Jewish and are commenting on the legitimacy of patrilineal Jews: your denomination of Judaism may not halachially recognise patrilineal Jews - but at least show some basic respect to the fact that theirs does, and be quiet
