I have never heard of Filipinos claiming Amerindians as Filipinos. I live in Canada and we can see Natives in the casinos chilling. They have features similar to ours but we never claimed them.
@prau123. I've seen those films and love them but most Filipinos haven't seen them unfortunately. I don't follow boxing but even if Filipinos know those guys, they don't know they are NA.
it's only me who are interested in here. Some of the North American natives have a similar look to us, it's natural for us to get curious and to study them.
As for the Caribbean and Latin American natives. some of them can have a similar look to us but way different from the North American Indians.
