Of course, but when you combine these themes and they are the only ones you paint, you are, not necesarily a fascist, but flirting with fascist imagery and clichées.
But as HerrKaiser notes, don't we all ressemble some Thomas Mann character, in this respect Tonio Kröger (a German-Iberian artistic mix, like this painter) with his infatuation with the blond and the blue-eyed ones, the happy, light, vitalistic, brutal and simple natures in the narrow-minded Danish duckpond. What is particularly interesting in the novel from a Romanov forum viewpoint is not only the fetishisation of the sailor suit so favoured by the royals, but that Tonio Kröger's "therapist", the painter Lisaweta Iwanowna, is a Slav. Does Thomas Mann imply that the Slavic races are beyond this north-south dichotomy of life versus art?
