Grad School Question

I am applying to grad schools in the Anthropology and Sociology Field. My goal is to use the knowledge I've learned in these fields and combine them with deaf studies because all over the world there a deaf communities that are ignored or even denied certain rights. However everytime I get calls or email from these schools the second I mention deaf studies they "don't have it" or they've "never heard of it". I feel these two fields will help me better understand certain cultures and why some societies neglect some communities within the same society but should I just go for a masters in deaf studies and education?
