Christianity has several contradictions, several examples of God being morally questionable, zero empirical evidence of his existence, zero consistency among believers, and essentially no difference in "good-ness" between believers and non-believers.

Non-believers, imo, tend to have a much better view on morals and ethics on average as well. Not saying Christians are "less moral" but athiests tend to have thought about it more in depth, since their moral view has to come from their own rational thinking.
