The two conflicting political beliefs
One group believes we are ruled over by benevolent leaders, while the other believes we are led by murderous psychopaths.
The first group tend to believe whatever the government and the leading institutions say, whereas the second group takes them with a grain of salt, or perhaps a full shaker!
As a result, these groups are rarely in accord!
This is fine as long as one group doesn't, by misuse of government power, force the other group to live by their values.
In this case civil unrest becomes likely.
