That’s a common mischaracterization of the atheist/agnostic worldview, but it’s not an accurate one. The absence of a divine god or a religious dogma doesn’t imply social anarchy or the absence of morality. There are still rights and wrongs, and behaviors that are appropriate or inappropriate, based on simple human empathy and compassion, as well as the requirements of the social contract. We can pretty much all agree that murder, violence, and theft are unacceptable, and that every person should be treated with honesty, kindness, and respect. I’ll assume you try to live a good life and treat others well — but why? Is it because that’s how your god requires you to act, or because it’s the right thing to do? I hope it’s the latter, same as me.
