Please review Wikipedia:Categorization, specifically WP:CATDEF. Categories should be supported by sources as defining traits. For Alt-right anthropologists, every article would need a reliable source for this term first, and only then could a category be applied. Please also note that the term alt-right was coined (or popularized) in 2008. It is unlikely that anyone who died before then would be labeled this. Please make sure sources directly support this term, to make sure it's not a neologism. You may find Category:Scientific racism more useful.
