It seems like whenever an orthodox rabbi wants to win a halakhic debate he compares his opponents (or their position) to Karaites (or Karaism). To be honest, these comparisons are sometimes the best publicity Karaites can get. I can name dozens of Karaites whose first introduction to Karaite Judaism was through a rabbi who criticized them for holding Karaite beliefs.
But there’s something deeper and more troubling going on with these comparisons.
