However, I have spent the past four years actively involved in the debate community. Currently I am working in the Senate on defense, international relations and human rights legislation. Being topical is a good thing. Other than that and having an advantage I am open to your strategy. I have no specific dislikes in this arena.
Topicality is a check for abuse in the debate.
It can be over used, this is obnoxious. As long as there is clean debate on the issue then it is fine. If their is a challenge to a piece of evidence then I will probably call for it at the end of the round. These disputes must be made and handled carefully. You have to be able to back up your argument.
