But coldtea confirmed I was right that he is a socialist.

The reason I was able to correctly infer he is a socialist is he was following a familiar socialist-marxist position. This is that democracy in capitalist countries is a shame, everything that happens is decided in secret by the rich people, who control the media to trick the population to go along. According to this view, true freedom of speech and democracy are possible only under socialism.

Attaching a label to someone is the most significant act in analysis.
