We're not allowing other people to comment on the debate after it has finished. The point of the debate, and subsequent voting, is to prove why your stance has more validity than the opposing opinion. If you want to discuss the debate on the side, we can use the existing thread for that, or create a new one.
As far as the voting itself goes, the point of giving an explanation is to weed out people that simply vote because they like person x, or they're voting because they agree with person y's opinion, but aren't voting for them based on the merits of the debate. You don't have to agree with someone's stance in order to vote for them, you vote for them because they did a better job of debating their stance than the other person.
