I'm not personally that bitter about it, but I understand the sentiment.
One thing many people, especially people with children, don't seem to understand is a) not everyone likes kids, b) not everyone wants kids and c) not everyone is able to have kids. For people in these groups, it often seems like other people have the attitude that "everything is about the children." If you are a woman who has had five miscarriages trying to have her own child, this can be offensive. If you are a homosexual couple in a hostile state that doesn't allow you to adopt, this can be offensive. If you simply choose not to have kids, this can be offensive. In fact, the tax breaks and other benefits offered to people who do have children can be seen as discrimination against those who do not, which can be offensive. Just as Christians usually do not realize how pushy and in-your-face their expression of their beliefs can be to someone who is not Christian, people with kids often have no empathy for those who do not.
I don't know if this explains the OP's position or not, but it's something to think about. The world is not all about the children. They play a major role and deserve protection, but don't assume everyone feels the same way you do about them.
