The only reason the ethnicity of Jared’s family came up was that Jared had claimed Mein Kampf as one of his favorite books (not to mention the Communist Manifesto). Tierney explained to Mother Jones that Jared liked to push people’s buttons and had likely listed Mein Kampf to annoy his Jewish mother.
Normally, you’d think that the word of a long-time friend would be pretty solid evidence. Surely Bryce visited his friend Jared around Christmas (or Hanukkah) and remembers which holidays his friend’s family celebrated or didn’t celebrate.
An individual at the Jewish Telegraph Agency however appears determined to contradict Mother Jones. Does he accuse Bryce Tierny of being a horrible anti-Semite, making up a false accusation of Jewishness? Strangely, No. In fact, the JTA individual suggested that Jared Loughner himself may have been lying to Bryce Tierny.
The most important point is the statement by Jared’s friend, Bryce Tierny that Jared’s mother is Jewish, followed by the fact that all the names in Jared Loughner’s lineage turn up in Jewish surname databases
