"Disingenuous" means "insincere, dishonest, deceitful, duplicitous."
If you didn't mean to say that I am duplicitous, than I accept your explanation an apology, and will consider it over with good will restored.
As for the argument about the meaning of "bowing," very few symbolic actions are perfectly clearly defined as are terms in physics or mathematics,and that's a good thing to keep this ambiguity in mind when conflicts arise.
The wisest policy is, when people show gestures of respect, interpret it respectfully.
