According to whom? I never signed up for this.
The only "responsibilities" (what a loaded word; you automatically imply we're irresponsible if we disagree with you) I acknowledge are those I took on of my own volition.
Most good and considerate people who aren't complete shitheads
Most higher organizations/clubs/associations/families engage in philanthropy and charity, most religions espouse the virtues or godliness of good will towards others and, again, most people who have the capacity to feel will agree that extending that empathy towards others is a good thing.
The point is most people, especially those who see things from a higher level socially and intellectually, recognize the value of compassion and selflessness.
Someone who balks at the suggestion that they have a responsibility as a good person to be considerate, who embodies the message of Ayn Rand's Anthem, might be considered immature. A shithead, even.
