As for causing a family "war", since his kids are living under Grandma's roof if I were her I'd tell him until he can provide for his family himself, he doesn't get to tell me what I can and cannot talk about in my own house!!
This is an astute point. JW or not, people can say or think whatever the fuck they want under their own roof. Especially when they are elderly and have put up with his bullshit for years, all culminating in the current situation of a hopelessly broken family. I’d be like: “oh NOW you are concerned about your kids? I speak about my own views to my grandkids in the house I’ve lived in for decades and you threaten me by limiting contact with them? The same guy who left them one holiday season to bang hookers in Thailand? The same man who moved an hour away because he didn’t like that our daughter wouldn’t take it up the ass and wouldn’t tolerate him seeing other women?”
There are so many people who are getting shunned by JW relatives. By all accounts, the in-laws have been quite lenient towards them per JW rules. They even allowed him to build an apostate studio underneath their living quarters! Most would take the random JW comment for what it is and count their lucky stars their kids have a seemingly functional relationship with their grandparents. Not Lloyd. He relishes in fucking everything up and sticking his big nose into everything. This was something for Dijana to deal with, not him. Her parents, her family home.
That family desperately needs an enforcer. My family had one - a biker type uncle who would kick the living shit out of boyfriends/husbands who fucked over any of his children, grandchildren, nieces and nephews. Someone who would drive to Zagreb, confront that fat fuck in the street and drop him to the asphalt for speaking to his auntie like that.
