This is like if David Icke, the guy who constantly talks about alien lizards, was asked to join (and joined) the govt committee about aliens not being real.
Brother Nathaniel joins the "middle of the road, let's not offend anyone" sspx.

This makes no sense.
The sspx's excommunication didn't have the "shock value" that new rome wanted. I think this Nathaniel addition will create a situation where the sspx will be condemned as anti-semetic. They need the laity to be "shocked" and scared of being Trad.
