Read her data on cousins marrying and the genetic effects, and where it is occuring in the world. Hint, it isn’t happening with the Amish....
I posted a video (Analysis page - top) of photos that were taken and still can be found about a site in Baghdad discovered by a joint patrol of 82nd AB and Iraqis - the handicap children found...basically sold to these people - for sexual exploitation and left to die...this is the effects of cousins marrying each other - and if it happens - they sell or kill the child...the part of sexual exploitation was left out - the part of them being transferred to Karbala (my area of operation)was put in as something good — these boys went right back to being exploited or killed to get rid of them due to the negative press in the future...when talking to the locals - they thought nothing of it!
