Education about the activity itself occurs at tournaments. In the past I have not liked evaluating theory issues. This is rapidly changing. Please feel free to make, explain, and extend well developed theoretical objections to your opponents strategy. Avoid reading scripted theory arguments at top speed.
Most negatives do a very poor job of debating topicality.
I am not convinced that extending Title VII to a previously excluded area is topical. Affirmatives who exclusively rely on nexis evidence that use words in the topic in some random fashion as well as the traditional whines about the negative having some evidence are in a world of hurt. A good idea if you have no case evidence. You need a net benefit. Feel free to make and defend multiple permutations.
