Focusing on just one word of that troubled sentence (is), to reflect the truth in the world and not initiate a falsehood, you would need to either change that to read something like I propose is or cite evidence that the term is already in existence and has the same definition you give it, because you cannot of course say something “is” when it “isn’t”.
If you would like to go for the second option, the onus is on the writer, not the reader, to give the exact reference and quote it accurately.
If you would like to go for the first option, you would need to expand on it. Now you’ve just given a definition. Support it with more work, ideally exactly citing previous work, to improve reception.
