I only have a few differences between my personal belief and theres. Such as there keeping of a lunar sabbath.

But I've noticed over the pass years. How they disagree with Rabbinical Jews on literally everything.

But why are Karaite Jews still considered Orthodoxy?

That's sort of like Protestants having the same religious belief they do now. But are under the title Catholicism. I never understand why Karaites were considered Orthodox.

I think they should become a splintered organizations. Sort of like Karaite Judaism as is Roman Catholicism.
Update: Yes Karaite Jews are considered Orthodoxy. Check it out. Do research on Karaite(ism). I choose them over Rabbinical Judaism.
