Get the children. And one gets the future. As the current and older generations die the earth would be their inheritance.
Therefore homeschool and filter and inoculate your children against modern culture lest he/she fall into the pervasive indoctrination.
Neither expose them brainwashing nor leave them unequipped in dealing with brainwashing.
Sheltering your child is important but so does controlled exposure like inoculation so as to help him/her build up resistance with the tools they need to minimize toxic influence. And influence the culture in the other direction when possible.
Notice that while they themselves are sterile. They seek to perpetuate the toxic memes horizontally among those who still have children.
