Saying things violate Paul Grahm’s principle isn’t used here to dismiss ideas, only to, as you said, put the burden of proof on them as being prima facie false. I don’t think that “heretical” was quite the same way, nor are “racist” and “fascist”, etc.
I would never say “prima facie proves” so maybe we are using some words to express very different concepts.
