I was recently having a discussion with a fellow Karaite regarding the various stages of Karaite thought. In brief, he summarized that there were (in his estimation, as well as others) three main periods of Karaite halakhic literature: (i) early; (ii) late; and (iii) very late. Today, I am going to use the example of women and techellet and demonstrate how each of these periods approached this issue.
In my opinion, we can trace the decline of the Karaite movement by looking at the methods these sages employed in explaining our religious conclusions, regardless of whether we agree with the ultimate conclusion itself. At the end, you get to vote who got it right.
