Then I just don't really know what you're proposing exactly. What does 'enlarge the term' mean in practical terms? Are you calling Klingons Klingon or Human or both? As for the second part, I was referring to your claim that we should use 'Terran' as the alternative for 'Human' since you want to use the word 'Human' to mean something else. So, if I understand you correctly, then 'Terran' would be the standard word to refer to the species Homo Sapiens. Which is fine for Homo Sapiens, but kind of insulting for the other intelligent species of Terran that aren't in any way Homo Sapiens.
