Dr. Clayton Valli is one of the ASL poetry pioneers. He was the first one analyzing rhymes, rhythms, and alliteration in ASL poetry in his doctoral dissertation.
The video clip shows one of his well-known ASL poems, Dandelions. In this poem, Valli likened dandelions to Deaf people.
Hearing people have been trying to eliminate or "hearize" deaf people for the past thousands of years, forbidding sign language, and so on, no matter how.
Yet, nature stands strong and beautiful. Sign language is all natural that nothing can replace it, too natural for deaf people, and as natural as spoken language.
Disliking dandelions is a symbol of cultural perception.
