Shalom Brett,
It is true that the result information FTDNA sends you is very technical and sometimes difficult to interpret. They try to give summary type explanations to make it more simple and informative. FTDNA really cannot make a determination if you are "Jewish", but with your genetic haplotype, they can determine how you compare with the broader Jewish populations and their common haplotypes. If you read other articles on this website, you'll learn that there is a historical difference between the Jewish and 10-Israel populations. There are genetic overlaps, but the 10-Israel/Ephraimite population is much larger than the Jewish population. So even if you don't appear to have Jewish Ancestors, it is very possible that you may have Ephraimite ancestors. Some even have ancestors in both groups.
Which test did you take? And what Haplogroup(s) were you placed in?
