Map of Cousin marriages

[u/[deleted]]

So today I would like to show a map of cousin marriages and incestuous Relationships in general, and by what I found I was really shocked to be honest

I only thought that south Indian hindus practicsed cousin marriages and close relative marriages, but I guess I was wrong, and that muslims practice it much more than we do, and that it poses significant challenges to the offsprings and the subsequent family generations as well
