It seems to me that one of the common sticking points of any argument is a difference in values:
- "I value mountaineering - you think it's stupidly dangerous"
- "I eat too much - you think I'm a drain on the national health service"
- "I value freedom - you value security"
It's very difficult to appreciate other peoples' values, which is one reason why we should all have an equal vote in Interactive Democracy... and not be governed by the values of a small group of 640 odd MPs.
