Pedos are usually abused as children themselves

Most likely, your husband was abused as a child himself.  Your mother-in-law's reaction shows she knows what's going on in the family.  There are many Satanic families in the US that practice pedophilia as a family tradition for multiple generations.  Why they do that and for what purpose and who are they is a very esoterc question.  There are a lot of information on the internet if you want to do deep dive (a rabbit hole, so to speak).  Just to give you a hint:  Jeffery Epstein, the most famous pedo in the world, was also sexually abused as a teenager, from the material I researched.  Bottomline, be careful when you date and marry white guys.  Choose men with faith/family value/work ethics, etc.  Don't be dazzled by external forms/looks/manners.  -Sorry for writing in English as I don't have a Chinese word processor handy.
