You twist the focus here to the haplotree, because it suits your
goal. Fine.

But the "haplotree" is merely a subset of the true Y phylogeny. In
the real world, clades require no "SNP mutations" to define them.
They exist whether such SNPs exist or not.

That self-referential "cladists" are self-absorbed enough to believe
that the clade only exists AFTER they discover it is a source of
amusement to me and confusion to many.
