Specifically, fascism in the context of the ideology prevalent in countries during WWII.

I think your definition of fascism is incomplete

Fascism always includes all the things I laid out, including a commitment to conservative social values

I mean it isn't though. If anything, your application of the term is far too broad.

Nationalism is, in a political sense, synonymous with fascism

My application is more narrow than yours

For instance, the Modi government is a fascist government, the BNP is a fascist party

Because again, conservatives are not the individuals who would overthrow the preexisting government.

That is simply not a part of conservatism.

Conservative social values? Do you mean conservative in the context of the US or conservative in the since of preserving existing policy?

I’m talking about conservative social values, not conservatism, though fascism/nationalism is of course on the far right of the conservative spectrum

And is within conservative movement’s, as it is in the US and as it was in Germany in the 30’s

The KKK is a fascist organization for instance

As was the silver legion

It actually isn't. Nazi Germany, for example, had elements from both the left and the right.

So you mean conservative in the context of the united states or whatever country you call home then

GG @Soup Can Sam, you just advanced to level 1!

The Nazi party grew out of the conservative German parties

Conservative according to what though?

The more moderate German parties believe they could use the Nazis to drive up populist support for their coalition

"conservative" isn't a catch all term with a set definition in terms of social implication

Conservative according to local tradition

Its entirely reliant on the current state of affairs and what society you are talking about

Well, sort of

Ok well then according to local tradition, the Nazi's were extremely progressive

Social conservatism is always about the supremacy of family values and a return to a more “upright” time

You’re conflating the social and political here

I'm really not

social conservativism is still directly related to the current society

So when I say German conservatives

I mean the German National people’s party

The conservative German Party

The Nazi's can't be grouped into either left or right because they literally utilized both ends to gain and maintain power.

Who wanted the Nazi party (which was to the right of them) to be a bulwark against the leftist parties

No, the Nazis were a far right party

They can be grouped only on the right

Just as the communists can be grouped only on the left

Fascism is a far-right ideology

Despite the Nazi's having socialistic elements?

The Nazi party didn't grow out of conservative parties, it grew almost entirely out of the revolutionary parties and straight up killing political opponents

No, it literally grew out of the conservative parties
