The public doesn’t owe anything to academics; whether or not they decide to pay attention to literature of a certain field, it is their choice. I was merely stating my observation that while many seem to consider it worthwhile to pay some level of respect to physics or mathematics, fewer appear to do so with regards to sociology or media studies. Are such attitudes justified? Perhaps so, perhaps not - but either way I find nothing perplexing that the public does not respect all fields of inquiry equally.
We're not talking about "the public" generally, we're talking about someone who has thought about a topic and possesses enough interest to write about it. One would think that in the interest of intellecutal honesty they would investigate previous work. If they haven't, it's a valid point of criticism of the work, and I have criticized the work on that basis, just as I would criticize someone writing on space-time who hasn't bothered to look into Einstein, or someone writing on electronics as if they're discovering Kirchoff's law for the first time.
