What was dr. susan gratia-hupp definition of the 2nd amendment and how did it differ from congress’s definition?

For a little background, Suzanna Hupp is a former Republican member of the Texas House of Representatives and a strong, leading advocate of a 1991 bill for citizens' rights to carry concealed weapons. She has written a book detailing her experience post-Luby's massacre and how she ended up in Texas's House of Representatives. 

Anyway, Susan Gratia-Hupp's definition of the 2nd Amendment was that it was not for recreational purposes like hunting, but rather for self-defense. The constitutional and congressional definition did not specify self-defense vs. recreational purpose. This helped her significantly in the fight for concealed weapons. 

Hope I could help!
