@philosopher – I was actually speaking to the OP, whose barely concealed racism is showing once again. Sorry for not being sufficiently clear.
You can cite whatever rulings you want.
Keep in mind: (1) the contentiousness of the issue; (2) the fact that Radvaz and Rav Ovadia are sufficient to rely upon, even if some sort of giyur lechumra or formal renunciation of Karaism is required; and (3) keep in mind that there are two Ethiopian communities in question here, the larger of the two definitely being safek akum and the other one being more likely Karaites. But I’m no expert and this is definitely above my pay grade.
Again, no issues with you at all. My issue is the barely concealed racism and bigotry that the OP constantly spews, as well as his blatant disrespect of anyone who is not Yeshivish/Chassidish. It’s tired, old, childish, divisive and quite frankly irritatingly stupid.
