The basis of you dismissing their political and economic success is devoid of a single political or economic argument and in fact consists entirely of a bigotted stereotyping. Chlamydia is a germ disease not a genetic one, and those vikings are perhaps the most individualistic people on earth. So your stereotype lacks even the scent of truth. On the contrary their success comes from that very individuality and truly treatimg each person as unique. They do not misstreat women bevause they see them as individual people not part of some group they expect to share anything.
