philosopher? I stand by what I said. Most Ethiopians who came to Israel are practicing Christians
You are repeating this without any proof or at least an explanation how you came to this conclusion. There were similar claims about Russians here, I looked at the numbers and they were not correct. I started looking up numbers here and they do not look correct either.
If your claim is based on personal observation, you may be confused by the timeline. Judaic Beta Israel were the first to come to Israel, possibly before you were born. Many of them did not want anything to do with remaining converts. The more time passes, the more remaining ones are those who come from converts. I do not know enough whether they are serious about their teshuva or just opportunists to get out.
