Not necessarily: the half of my family which doesn't consider first-cousins taboo is from a place where there is a lot of genetic variation. The half which considers second-cousins taboo is from a place with a lot less genetic variation: avoiding "mixing blood that's too close" requires going further away when you know that climbing any branch of the family tree will lead to a common pair of ancestors eventually (just as a completely random piece of data, a study of the family trees of my 40-students 11th-grade class, where each tree was available going up to 1700, found common ancestors for any of us with two to six other students; we were in the area the no-cousins side of my family hails from).
