A name is nothing more than that. Take the name "Liberal". We have taken it to mean a party which occupies the middle ground. In the dictionary it says something like:

"willing to respect or accept behaviour or opinions different from one's own; open to new ideas."

In the US it seems to have become a term of abuse thrown around by the right. But in Australia it is a right wing party, and you cannot imagine that dictionary definition being applied to the government of the unlamented Tony Abbott.

The Nazis may have called themselves National Socialist, but their values are far removed from those of equality and justice put forward by people like Jeremy Corbyn. Their model of central control is far removed from the workers' democracy advocated by the Socialist Workers Party. And their values were not those of the planned economic model of the Union of Soviet Socialist Republics. The Nazi system was fascist, racist and anti-semitic, but you could not call it planned.
