One’s an economic school of thought, the other a political one, so obviously you can have both at the same time or even working together. Coincidentally corporate business is mostly anti-fascist right now because social diversity and progressiveness is where the money’s at
I can only guess you’ve used one of the words out of context. If it was fascism, I have nfi what the meme is trying to say by linking Superman to capitalism in the same way Homelander is easily linked with fascism.
If the joke instead about fascism, then maybe something positive and relatable to it would make sense. Patriotism is what I think of since Superman loves America, but shows little concern for anyone else and this sentiment could start festering domestically, especially if the love for country becomes ultra-nationalistic.
