Thanks for posting.
IMHO Natasha made the best arguments followed by Douglas. For anyone familiar with facts and history, IMHO Gideon came out the worst, relying heavily on lies and distortions. Mehdi seemed to play honest, but his arguments came across very lop sided and relying on flawed sources.
Most importantly, if the definitions FOR THE SAKE OF THIS DEBATE were given in advance of any side presenting their argument, the fact that the con side strongest argument was to challenge the definitions used as the premise for the debate, becomes one of the strongest arguments against their side.
