Yes, IMO is how I started that post. But lets look at your last statement:
True the belief is that jesus christ was michael the archangel but the point of the celebration is to remember that the "man" jesus christ died to cancel out the sin of adam that brought the curse of death along with it and that those excercising faith in christ might not be destroyed .If it is not a celebration to the Archangel Michael, than it is to a "man", equally as blasphemous.
