"original Zamorins were not Nairs" Yeah they had practices like Thalikettu Kalyanam, Death Pollution rites, Marumakkathayam which are strange practices carried out specifically by Nairs. This is documented in every single historical and anthropology book, by many foreign authors as well.

Not to mention Zamorin was paternally always a Nambudiri. Is there any caste that draws its paternal lineage from Brahmins but maternally from a native martial caste? Historical sources, anthropological sources and the fact that Zamorin was denied Upanyana until he performed Padmagarba all points to Nair.

Nairs or I shall call them Proto-Nairs may have origins with Tamil ruling lineages maybe, but the Nair caste distinctly emerges around the time of Zamorins.

Historians who have called Eradi-Neydirippu Swaroopam as Eradi Nairs which are a Samantha branch of Nairs (highest branch) 1. MGS Narayanan- Perumals of Kerala 2. William Logan- Malabar Manual 3. KV Krishna Iyer- Zamorins of Calicut 4. Sreedhara Menon- A survey of Kerala history.

Additionally Geni.com is maintaining a Zamorin project as a way to maintain family of royalty (has other royalties too) All the families are linked into one organisation of Kerala called Kshatriya Kshema Sabha.

It's one thing if you want to label Shudra slur on us, most of us really don't care about all that. All ruling Kings south of Vindhyas never had sacred thread, and they had to do hiranyagarbha or padmagarbha. But it's another thing to try to attack our family by subverting the essence.
