Atheist argues 'It's wrong because I don't like it'

As demonstrated in the link below, even high level intellectual atheists basically argue as these young men do, that something is wrong because they don't personally like it or a group of people don't personally like it. There is no objectivity to moral laws or rights in atheism. Atheism reduces to philosophical childish tantrums.

You will notice in discussions with people in general and atheists in particular that they think defining a moral standard justifies it. That is basic question begging. 'It's wrong because it hurts people'. Why is hurting people wrong? 'Because people don't like being hurt.' Why is it wrong to hurt people just because they don't want to be hurt? Look for the 'is/ought' fallacy.
