he rejected groups outside of state control. when I said you have to read the whole section, understanding it was implied in that statement, I didn't think I had to explicitly state 'you have to read and understand the whole section'

The whole document defines a socialist system where the state controls all resources, including labor, and the state is put above the individual.

Edit 'cause comments are locked:

He doesn't reject socialism, he rejects groups functioning outside of state, or not in sync with the state

Read this -> Fascism is therefore opposed to Socialism to which unity within the State (which amalgamates classes into a single economic and ethical reality) is unknown,

As this-> > Fascism is therefore opposed to Socialism to WHICH unity within the State is unknown and WHICH sees in history nothing but the class struggle >The State amalgamates classes into a single economic and ethical reality

Then he says it a little more clearly for trade groups > Fascism is likewise opposed to trade unionism as a class weapon.

The state is an equalizer, there are no classes under fascism, so if a group is divisive on a class basis, its not in line with fascism. if its not in sync with the state, its rejected.

But these groups are all good if they fall under the state. Their concerns are real and they will have an equal seat at the table under fascism.

>giving them due weight in the guild or corporative system in which divergent interests are coordinated and harmonized in the unity of the State

Theres a lot there, you getting it? He rejects class warfare and groups or philosophies that push it, because you know, fascism has eliminated the class divisions. When in sync with the state tho, those groups and philosophies get a seat at the table. There is no rejection of socialism, but a rejection of the basis of it as a divisive class struggle. He sets up a socialist state, where the state has control of all resources(including labor), but its totally not socialism because there is no class struggle or conflict under fascism as that problem was solved.
