Yes, but is it wrong because it's "objectively" wrong, that's the issue...
Yes, I think maybe that he has a completely different definition of "objective" than the rest of us do maybe, etc...?
Even if all humans could agree, and never disagree, etc, there still might be other places, or other situations/circumstances, or other "beings", etc, where things might still be or work or operate differently, that still might not think or agree with us always completely all the same, etc...
And is still therefore "not objective", etc...
Christians want to argue that certain things are always wrong, regardless of circumstances, because they want to set us up with the dilemma of needing salvation from our "sins" for having violated some kind of moral absolute law that exists apart from any actual context. However, some of us don't believe anything like that can actually exist.
That was the OT, and OC, that was always meant to go on and not actually save anyone until Christ came to end it and be the fulfillment/ender of it, etc...
Things are a bit different after that now, etc...
The OC was never meant for or ever made or meant to save, etc, or keep anyone or anything holy, etc, or "whatever", etc, but was actually made to do the opposite, and make sin even much more worse until Jesus came, etc...
Things are (supposed to be) different now, etc...
But unfortunately, we still have a lot of people (Christians) that have not fully accepted the new ways, or all of the NT/NC ways yet completely, etc, but are still just only believing and following the Old still, etc, or are trying to mix the two when they just don't mix, etc, this was a major problem from the very start of the NT/NC, and down through the ages, and unfortunately, still is still now today, etc...
However, some of us don't believe anything like that can actually exist.
It could maybe could or might with the true Highest Father maybe, etc...?
But, other than that, most of us think pretty much "no", unless a thing quite literally is all, (or none), (or both, etc), or else exists in a total and complete vacuum, etc...
God Bless!
