Just as there are places where eating canids and felids is not taboo - so too are there places where eating a primate is not taboo. A larger geography by far as far as I know.

By this argument and amount of places (not people), eating a primate might be less taboo than eating a canid or felid?

As an American, I feel the same cultural taboos and they’ve kept me from eating some things but I’ve been reconsidering. Horse and rabbit were delicious.

What about coyote or mountain lion though? Those are still but seldom eaten in America mostly by hunters.

Some people draw the line at not eating predators not because of cultural taboo but because of bio accumulation issues.

Fascinating ethnobiology and moral boundary discussion.
