The problem is the assumption that in most debates there are sides to be taken, and that there are 2 of them. It leads to shoddy journalism where "balance" means finding someone to debate another, regardless of the bizarreness of their position.
In the real world there are many perspectives on a given issue, and a lot to be learned by everyone through open discussion. "Both sides" mentality discourages this, and also tends to give too much airtime to extreme views.
