No. When it comes to morality you have given no justification for your assertions.Yours are subjective opinions anyway, we have discovered this much have we not?
But, atheists don't declare that. For example, It's not a subjective opinion that the Earth orbits the Sun.Years and years of atheists declaring the universe and everything subjective have led me to believe it has a remarkable similarity to a blind man leading another blind man into discovering it's all subjective.
Prove me wrong.
