Since you are for it, why don't you tell us what it means to you? Then we can get on to the meaning of "is."
Free Trade has two basic meanings, but both have the same implication and ultimately mean the same thing.
1. Free Trade is the idea that there will be a free flow of goods and services with standard sets of rules on both ends, both to and from the respective parties. There has to be at least two parties involved.
2. Free Trade is actually ratifying that into law on both ends.
Your turn.
