6 Wives, 20+ children, holy jesus!...and that image you shared, my honest opinion on it is that — that kind of mindset is retarded — why are people infatuated with bloodline? And infatuation with misery? And of perpetuating it? and of considering suffering a good thing?
On this particular part — "weak men plan, strong men plant" — yea, it takes much to plant, and nothing to plan; can definitely see who's stronger and who's weak.
My first reaction when I read his post, which religion allow to have 6 wives?

AFAIK most religions only allow 1, while Islam allow up to 4 wives, so it seems to me like his grandparent an atheist and his dream is to fuck with many healthy women. I know people can just go to prostitutes if they want to have sex, but some people don't want to do that due to health risk.
Most people who have many wives will do everything to earn money including illegal and harmful ways.
