On A Debate Why Couldn't I Answer Both?

I think you're a fine debater. You're able to understand both positions of the topic. This makes you an effective debater. You're able to foresee what the opponent may say and counter it.

That's the whole point of a debate to pick a side(for or against) and argue that point. you can add comments to the other side under the person that you want to discuss your point of view with and if they have their settings set to receive your comments then they can reply to your comments.
