@Zultar- I am not saying I go on there and copy other peoples ideas. Before I even go on the site I set up a concept map with research topics and arguments, I follow that up with research. Debate.org gives me a starting point, I can go on there and look up the topic I am arguing for/against and see what opposition would argue to strengthen my thesis and essay as a whole. For example right now I am writing an essay about allowing women to serve in combat roles within the military here is an example of a concept map I made for this essay: https://www.lucidchart.com/invitations/accept/260

I am still working on it, but once I am happy with my concept map I will go on the debate page add more angles that I didn't see while making my concept map, and then start researching primary documents to dismiss those arguments.
