I think Dali came to fascism later in life, but earlier he was in a communist group. I always wondered if it was a truly natural progression or just a consequence of wanting to stay in Spain under Franco and letting justifications become ideology.

Edit: looking this up, he stopped being a hardcore communist with the slow rise of fascism and after Franco consolidated power became a frothing at the mouth pro-catholic fascist. Seems like a day or do anything to benefit from power type deal, which I somehow find worse than true belief.
