Earlier quoted context omitted.
I wrote it in so nice way. I'm usually more harsh to people. Deciding not to have kids because it's too much of an effort is so selfish act. You're throwing away all the effort your ancestors put in to get to the point of you being alive.
You are normally "way more harsh to people" for making the very personal decision as to whether they will have children? You do realize just how offensive you are being? Whether other people have children is not for you to decide or deride.
This is probably the most offensive thing in this thread.
You are allowed to disagree with other people's choices. You are allowed to voice that disagreement, even publicly. People are allowed to think you're stupid for caring whether or not someone else has children.
Nothing about any of that is even remotely "discrimination" and to imply it's anywhere in the same universe as racism or sexism is offensive to real problems everywhere.
