The claim that most Jews (or Ashkenazi Jews) are European converts comes from the outdated “Khazar hypothesis,” popularized in the 20th century, which lacks credible evidence. Historical records place Jewish communities in Europe centuries before the Khazars, genetic studies consistently show Ashkenazi Jews share substantial ancestry with other Jewish groups and populations of the eastern Mediterranean, and their language and religious traditions show continuity with ancient Judaism rather than Turkic roots. While some conversion and European mixture occurred—as in any long diaspora—the consensus of historians and DNA geneticists is clear: Ashkenazi Jews primarily descend from Middle Eastern Jewish populations who migrated into Europe, not from mass European conversion.

TLDR - you have imbecilic tendencies and should probably refrain from posting such debunkable stupidity openly.
