It is a pointy edit because you are removing information not because you believe it not to be factual but to make a point that if youre not allowed to add material without a citation from a reliable source when another editor disputes it then everything must be sourced  If you were removing it because you actually did not believe that the Tappan Zee Bridge connects Greenburgh to Orangetown then the edit would not be pointy but youre only doing it to make a point about consistency  and that is the very definition of pointy editing  Cut it out please
