Jewish peoplehood, or nonpeoplehood is changing before our eyes. Even the 200 some years since the emancipation, is but a blink of time.
What does it mean to be a Jew if you don't believe in God and don't believe in Judaism and you're satisfied to watch your Jewishness blend with other colors and produce new colors, but cease to exist as a previous color.
Actually it means that you are part of a transition stage. If a previous stage of Jewish ungodness and unpeopleness produced an offspring of Marx, Trotsky and Rosa Luxemburg, we shall see what offspring are produced by the newest stage of unpeopleness, which is less tinged with self righteousness than that previous stage (and the murder it begot.) In previous generations Jews baptised themselves and ceased (?) being Jews. Today we mix and intermarry and have multiple identities and continue to be Jews, but also the new something that's a new color, not the same color as before. And in transition we are vaguely conscious of what we were and what we may become but superconscious of what we are.
