unfortunatly again is wrong
sturgeon's law is
nothing is always absolutely so
while Sturgeons revelation is
I repeat Sturgeon's Revelation, which was wrung out of me after twenty years of wearying defense of science fiction against attacks of people who used the worst examples of the field for ammunition, and whose conclusion was that ninety percent of SF is crud. Using the same standards that categorize 90% of science fiction as trash, crud, or crap, it can be argued that 90% of film, literature, consumer goods, etc. is crap. In other words, the claim (or fact) that 90% of science fiction is crap is ultimately uninformative, because science fiction conforms to the same trends of quality as all other art forms
even when you use it as you are, you are using it incorrectly as it refers that all art forms are just as bad as all others, it was intended to criticize the people that say a specific genre is bad as the same can be said for all other forms of the media.
so even in your use case you are wrong, and unfortunately you still can't prove i have shit taste as it does not exist.
