Philadelphia Confession = Hardshellism?

In his debate with Dr. W. P. Thorgmorton on the question "Who Are The Primitive Baptists," Elder Lemuel Potter said:

"He (Throgmorton) says we have not the Philadelphia confession of faith in any of our churches or associations. He says they have. It is not so much a matter of concern with me as to who have it, but as to who believe it and preach it. That is the question we are here to settle. We are here to identify each other by what we preach and teach; to identify ourselves with the Old Baptists on that subject. Remember, that although the Philadelphia confession of faith is still a “Hardshell” Baptist document some of the Missionary Baptist associations fight it. That is, the doctrine it contains. Not only a few of them, but take the country over, a majority of their ministers today preach the doctrine of Arminianism, the very thing that this London confession of faith denied when it was first gotten up."  (see here)

Is there any Hardshell apologist today who wants to come to a serious discussion as to whether today's "Primitive Baptists" believe and preach the doctrines of the Philadelphia Confession?  If it can be shown that today's Hardshells reject the teachings of that confession, though once accepted by their ancestors, does it not prove that they are not "original" as they claim?
