Such are the problems of language. I doubt the situation would arise where people would define a pig as an armadillo.
No, but discussion might arise when somebody might say e.g. 'atheists know there is no creator', and on the basis of it come up with a whole set of misleading conclusions.
No, we assume the meaning of most words (because we have to). But this discussion is hinged on the terms atheism, deism and theism. So we have to define those at least.
Agreed. Either contend them or if you cant be bothered, then dont worry about it.
'real' words, lol. Words can be used to mean different things, and a lot of them require a whole load of unsaid assumptions. For unknown words then sure, use the dictionary, but if you are unsure of how someone is using a particular known word, the best thing to do is to ask them, for the sake of clarity. Otherwise you just end up talking past each other. Language is a tool, after all.
Exactly - thats why I defined the words using the dictionary quite early on in the discussion as there seemed to be no common consensus on the defintions. And there was no objections, nor did I think there would be as its a fairly standard , universally agreed upon & ubiquitous definition.
Do you have a link to that definition btw,, I can't seem to find it

I posted the link earlier, search for atheism, deism & god in
www.oxforddictionariesonline.com or something like that
