And to be frank. Only fascists fraternize with fascists. It probably also contributes to the loneliness epidemic when no one will be their friend because of their racist/nationalist/sexist beliefs except other such degenerates (who aren't really their friends at all).
You aren't friends with fascists. Fascists have no friends, only temporary allies. NEVER TRUST A FASCIST: EVER.
Fascism is far far worse than loneliness for society. Fascism causes world wars. Loneliness doesn't cause that level of societal destruction. Fascism is evil.
