Addressing opposing arguments directly is not really a feature of arguing. That kind of good faith debate is more of a special case debate.

It's just not what public debate is. You see rookie politicians do it, but it's generally a mistake.

A huge part of what political debate is, is dominating the frame. The frame. The key facts, alternative or otherwise. The key question being debated.

Once those are established, the conclusion tends to be trivial.
