Which one of these would you support by increasing the numbers of these techniques in society ? Choose one only if you can

Debates or discussions?

You can of course use whatever ideas on the meaning of these two words you want, but my view of their salient points are as follows.
Debate : Use to attack or defend a defined motion , thus creating two opposing sides and deepening rifts. Used a lot by politicians who sometimes support illogical debating points just to ' win '.They sometimes can lead to war or drastic one sided action.

Discussion Used often amongst friends who do not always agree with one side or the other on anything but use the opportunity to learn. However sometimes how to shift a position at least nearer an overall conclusion or general concensus . Used more by diplomats trying to heal a rift between opposing factions.

Personally I wish all debates were banned especially in schools.
