Those people can DESCEND from L2D but you wont find a group of europeans who simply are L2D.
Um... Thats NOT how haplogroups work. You either have it or you don't. Which is why we use "frequency" and not "pure" when dealing with haplogroups unlike with admixture/autosomal. Yes there are certain areas where an haplogroup may have originated and is largely concentrated there but thats it.
