Godless is always used as a derogatory term.
No question.
It's a given.
I believe that godlessness has nothing to do with atheism. Since many atheists are good and can be godly, and some theists are evil and godless.
Within the Vatican there are godless people, I can promise you that. And it deals with Italian high prelates.
You can't even imagine the horrors that the Vatican walls conceal. There is no God in the hearts of those people.
So the fact that they call themselves Catholics is irrelevant.
Secondly: language is a tool that needs to express philosophical and theological notions. It's a tool. Metaphorical meaning of words is needed. Literal meaning of words stifles freedom of speech. It stifles the philosophical afflatus. It stifles debate.
When I am called 'godless' in derogatory fashion, over the course of my almost 49 years, it has ALWAYS been a commentary on my atheism, and NEVER been a comment on my wicked behaviour. My atheism is conflated with wicked behaviour (ie. I must be a liar, and damned) but it has never, ever had a single thing to do with an action I've taken.
I am yet to argue that some theists are good, and some not, and some atheists are good, and some not. My argument is with your use of a term which has meaning, and how you are using it in a non-standard way and not understanding the usage by the sources you are linking to, or how the usage is commonly experienced by atheists. Instead, you continue to defend the use of the word in a non-standard way for God only knows what purpose.
Once again....there is no God in my heart. I am godless. If you want to declare me wicked, just do so. If you instead wish to say I'm not, because I have a god, by all means articulate what my god is.
