Aikido is not an effective martial art
Pro has not composed his argument in round 1, and has forfeited round 2. The burden of proof is on Pro, since I cannot negate his resolution, "Aikido is not an effective martial art," without him presenting any argument for this claim. My position as Con, assumes that I am to negate an affirmation of the resolution, not affirm the opposite of a stated resolution. Pro also needs to define "effective," which could be construed many possible ways. Our argument must suffice in the closing round.
