No, actually they're not. Are you asserting anyone who rejects calling Mary the "Mother of God" is guilty of heresy? I've seen many people fall into the most gross, blatant, DISOBEDIENCE to the commands of God by bowing down to, praying to, worshipping and idolizing images and statues all the while profusely denying they are doing so to the detriment of their relationship with Christ. No one here has denied that Jesus Christ is the Son of God, that He is Almighty God in the flesh/God with us, so declaring we are heretics based upon some novel Roman Catholic dogma - that NONE of the Apostles ever taught or preached - is proving that some Catholics are only too happy to brand all non-Catholics as morons and dupes.
Do you think someone can go overboard in their "honoring" of Mary? I know many Catholics think non-Catholics don't honor her enough, but can she ever be honored too much?

The spirit of Yeshua was his ‘God’ part, not his body, which was the only part that Mary had anything to do with.
Yehova our Elohim has no mother, and the term ‘mother of God’ is grave blasphemy.
Yeshua had to give up his spirit, his god nature, in order to die as the sinless Lamb of God.

Anyone who says that Mary is not the mother of God has to deny that Jesus is God.
Mary can be honored superstitiously, just as God can be worshiped superstitiously. For example, anytime someone comes to believe that a certain prayer “never fails.” Or, an ignorant person could believe that a particular image has some sort of power.
But such ideas come naturally to the ignorant. They directly contradict the teaching of the Catholic Church.
Anyone who denies that Mary is the mother of God has fallen into heresy, because the Scriptures tell us:
Mary is the mother of Jesus.
Jesus is God.
