True Left

While undoubtedly there were men unable to find sexual partners in all civilizations, I am quite sure that only Western civilization that could come up with calling such men "incels" (with the connotation that someone is supposed to be assigned to provide them with sex). In all other historical civilizations, where polygamy was generally legal, it would have been considered entirely normal for some people to have more spouses and hence others to have none. It is only the (supremely patriarchal) Western civilization with its ban on legal polygamy that caused Western men to feel automatically entitled to one spouse each, and hence consider failure to acquire this sufficient reason to become misogynistic.
