What is Ken Livingstone's apparent problem with Judaism?

This article is incredible, here's the transcript of the video of Ken Livingstone speaking on a Press TV broadcast:

'Is not the problem here that when Zionism was conceived of back in the 1880s, the world was one that accepted racial division… The Germans talked about anyone of German blood, even if it had been a thousand years since they left, able to come back. The world broadly accepted this racism at all levels, and that was the origin of Zionism – ‘every other group is racially selective, we will do it’. We see that today in this ridiculous situation that that whereas Christianity and Islam massively goes out there to convert people to its [sic] faith, it’s very difficult to convert into Judaism. I think it’s a real problem, there’s this racial exclusiveness that has its origins in that dreadful time… 1880s, when all nations suffered from it.'

 Here's Alodya's explanation of where Ken Livingstone is WRONG:

'As ignorantly wrong about the history he claims to be drawing on as he is about the teachings of Christianity and Judaism, Livingstone targets Judaism as a different religion that is racist and intolerant, unlike Christianity and Islam. His “history” of the conversion rules of Judaism being based on nineteenth century German racial exclusivism is a total and malign fantasy calculated to represent Judaism and Nazism as having the same roots. Equating zionism and Nazism are central features of anti-semitic anti-zionism.

Making Judaism difficult to convert to goes back to Talmudic times,  not long after the period of Rabbi Hillel and Jesus of Nazareth and although the Rabbis made it more difficult in the centuries following the Jewish Diaspora, has nothing to do with the rise of political zionism in the mid to late nineteenth century.

Judaism is not interested in race. A child is Jewish if he or she is the child of a Jewish mother, whether he or she is black, like the Jews of India, Ethiopia and many parts of the Maghreb, or pale skinned, blond haired and  blue eyed, like some of the Jews of Poland  and Russia, frizzily dark haired and curved-nosed like many of the Jews of Germany, or has the characteristic skin colour and eyes of the children of Jewish converts who came from Japan and China. Anyone can convert to Judaism, provided they are not the children of a sexual union ruled illicit in the Torah, such as an incestuous union. All shades of zionist movement (of which there are many, both secular and religious, socialist and economically conservative), have always accepted that anyone born or converted according to Orthodox Jewish rules is eligible for citizenship of the Jewish state, wherever they live in the world.

Religious zionism however goes back to the first Psalms of the first period of Jewish exile to Babylon, which yearn for the return by the entire people to the homeland, both the land of Israel, and Zion-- the City of Jerusalem. They have been sung and chanted by religious Jews everywhere in the world as part of the prayers which accompany every meal they ate for almost two thousand years and continue to this day. Every  orthodox Jewish wedding going back to the earliest exile days has begun with an invocation to "Let us go up to Jerusalem" taken from the Song of Solomon and other Hebrew Bible texts'

 What is Ken's problem? Whatever it is, let's amke sure he doesn't get elected tomorrow.
