Yes, child brides are disgusting but that is what Joseph Smith practiced and so do the flds.
The flds are not an off shoot, the SLC lds are (I think from the SLC lds there are about 150 off shoots - not sure about the number).
Other than that, I am not sure what your point is here.

The numbers do not support that: 10k FLDS and 5m LDS. There are many fundamentalist sects from every religion that can be described as more original or closer to the origins of the religion than mainstream sects. Mainstream religions are not described as offshoots.
