Are you SDA? I'm guessing you are but you know you can't possibly admit it. Nobody but SDAs listen to Doug Bachelor, their current champion of da sabbath.
To reiterate...
You'd be surprised how well informed on many various ministries and their doctrines many a MAD outside of TOL is.
Your often "one size fits all" is blinding you, once more.
Am presently reading a work by SDA's E.G. White, myself.
Regarding the SDAs as a movement; one can learn much from them about the OT/NT one might not have considered.
Their confusion as Adventists winds them up so focused on the OT/NT as sort of pseudo-Israelites, that they end up bringing out things at times that would often be very sound were such things allowed to describe/be allowed to address who such things actually belong to - Israel*.
As for Interplanner; his beliefs are obviously more along the line of a strain within Reformed Theology (which is what his Partial Preterism, more or less, is).
More or less, in that, from what I have observed, he obviously holds to points of departure from Partial Preterism he has arrived at on his own.
No need to characterize the guy beyond the obvious just because his views and opposition are so obviously his own odd mix of this and that.
His conclusions and assertions expose his mis-fires and there source all on their own, more than adequately.
Rom. 5:8

* Just goes to show once more that this side of "that which is perfect" The Spirit now reveals His Will through The Scripture - even to the lost and or confused.
What such read into said revelations is the culprit.
As in "So then, Faith cometh by hearing, and hearing by the Word of God" BUT Israel both failed to Believe Moses' writings, and changed his intended meanings, in their ignorance, Rom. 10, John 5.
