Well it seems to follow pretty naturally that if you think that division is a problem, then being aware of how your attitude is the definition of division seems pretty important.

I would hope it might help you with your observation about the division of the country, and with your feeling of irony on another subject, and using both of these skills towards understanding.

So for the situation in general: if enough people are less divisive, perhaps a less divided country can occur.

I suppose by helping people become open to other, possibly more reasonable, options.
