1. Didn't allow open debate
2. Restricted language in order to make it impossible to disagree with it
3. Didn't give people the freedom to make up their own minds
When people seek to restrict definitions so that "2+2=4" is the only possible view, this is Orwellian.
When people say things like my boss should fire me for thinking "2+2=5", this is Orwellian.
This is NOT Orwellian.
