No, I don’t care if I’m considered selfish for not having children. You seem to think that if people aren’t naturally inclined to follow your example, that shaming them into it should be sufficient. That is clearly isn’t apparently is the problem, so to sum up your viewpoint:
”it’s a problem that I can’t shame people into doing what I do by calling them selfish! How dare they want to live according to their own desires, rather than by mine!”
Ironic.
Aside from that, you seem to view human behavior through glasses so rose tinted it’s more akin to looking through bloodstains. If anything, there is now more focus on being mindful of the needs and rights of others than there has ever been, at least in the west.
