snoot,
You only think it proves your point, but it doesn't. All it proves is that you are a poor sport, and that you don't know anything about formal debate.
You don't know that because you don't know the rules by which formal debate is judged.
For what it's worth, to argue that your opponent proved your point for you earns you nothing in a formal debate; and because you wasted time saying it, it shows that you don't value the limited time you have for each response, and therefore you will likely loose the debate.
Rule #4 of formal debate is the essence of the brick wall principle within debate.
That rule states that arguments must be extended throughout the debate to influence the decision.
The essence of that rule ...
To extend an argument means to pursue the issue from speech to speech. The idea is not merely to repeat what was already said, but to offer new analysis or evidence of why you are still winning this argument even given the other team's last position on this argument. As a general rule, if judges do not hear you extend an issue in the final speech for either team (2NR or 2AR), it will not count. These are considered dropped arguments and the judge will disregard them.
