Yes, haplogroups are defined because haplogroups are clades, and clades are
defined, not discovered. They're defined by the researcher building the
cladogram who decides on the traits to be included and makes the polarity
determinations for those traits. It's SNPs that are discovered, and I'm not
aware of any "hobbyist" ever discovering one.

There are no Jewish "clades" (beyond individual families) any more than there is
a Jewish "race," unless you want to completely divorce the word "clade" from its
cladistic meaning, which destroys its usefulness as a scientific term.
