Trinitarians who hold that Jesus is divine only: do you realize that your position is heretical?

"Chalcedonian Box" by a Trinitarian

I've noticed here on Y!A that some Trinitarians reject the duality of Christ: they reject the Hypostatic Union, and say Jesus is only fully divine. (They thus reject the Trinitarian apologetics of Matt Slick on carm.org.) Perhaps they do not realize that this denial may amount to monophysitism, the position that Christ has only one nature: divine. The orthodox Chalcedonian position however is that Christ maintains two natures: divine and human in one person. Trinitarian Christology is dyophysite not monophysite, and as monophysitism is contrary to the orthodox dyophysite Chalcedonian Creed (AD 451), it has always been considered heretical by the Western Church and most of the Eastern Church.

Thus, I'm wondering if the Trinitarians who reject the Hypostatic Union here on Y!A know that they are spreading monophysite heresy?

Note: I'm talking about Trinitarians who reject the Hypostatic Union, not Oneness believers.
Quotes from Trinitarians I'm referring to:

"after the resurrection, he had a "glorified" body, a body made not of flesh, and not subject to the same laws of physics"

"he had blood when human but not anymore...HE WAS BOTH but now spirit.."

[Found in response to my question "Two questions for Trinitarians?"]

(Not included is one who deleted his comment and another who had his comment deleted when the question he was responding to was deleted.)
[Referring first to my question "Trinitarians: How can Jesus be fully man outside of earth's atmosphere?" and second to my question "Jehovah's Witnesses, why do you reject the Trinity?", where user Surfari [AKA Crosseyed] said according to what I remember, in substance: "As if he (Slick) is the authority of the church!"]

Additional Details

@ David H: I'm not talking about "sincere ignorance" but willful rejection of the Hypostatic Union. They read Trinitarian apologetics like Matt Slick's on carm.org on the Hypostatic Union and reject it. One vocal Trinitarian [Surfari/Crosseyed]  here even mocked him and his apologetics.
