The AHA symbol represents a set of theological propositions:  the five tenets of abolitionism. While the symbol is an acronym for the phrase: Abolish Human Abortion, there is even more meaning to it.

The first "A," which stands for "Abolish" represents higher law or higher principles and is right-side-up. The second "A," which stands for "Abortion" is upside down because it is wrong. The "H" stands for "Human," but also stands for the first "A" (higher law) abrogating the lower "A" (man's law).

The "H" is also made up of two lines, each of which is an "I." These two I's stand for the two theological propositions that will destroy abortion: the Image of God in man which is what makes abortion wrong, and the Incarnation of Christ who is the driving force in the Abolitionist Movement. This video is a detailed explanation of this symbol of the Abolitionist Movement.
