founding fathers and constitution rollback

All these disruptions at town meetings and all this tea party business has got me worried as a citizen and a black citizen. at a meeting by a senator a woman stood up and said she wanted us to go back to what the founding fathers meant and follow the constitution. if you think about it a lot of the amendments that are important to women and black people are in the constitution after the founding fathers were dead.
