I don't think it is irresponsible for a woman to choose not to marry or have children. Everyone has the right to make such decisions based on their own values, life plans and personal circumstances. Responsibility or not should not be defined by marriage or reproductive status, but by how a person treats his choices and bears the corresponding consequences. Different people have different life goals and definitions of happiness. Some women may choose to focus on their careers, take care of their parents, devote themselves to social welfare, or simply enjoy an independent life. These are valuable and respectful life choices. It is important that everyone can make decisions that are truly suitable for them, rather than forcing themselves out of external pressure or traditional expectations.
