Intelligence is the name of a journal, the name of a television show, and the name of a rock band. While I'm sure none of these were within the context of your question, the point is that words are used by different people not just with different perspectives, but also for different purposes. Within the milieu of this forum, the words could still be used by different people for different purposes. I've seen discussions (in similar forums) wherein which posters were vigorously defending their perspectives in this regard, when the reality was that they were talking about completely unrelated things (and yet still insisting they were talking about the same thing, and the other person was "wrong"). I find such petty arguments inane. They serve no purpose other than to give people a context within which to throw silly slurs at someone else.
So in that light, I think it is worthwhile to avoid disputing how someone is using a word.
All of the definitions you put forward are definitions of something. There isn't much point in disagreeing about the use of the word "intelligence" to label that which is defined by each of the definitions you've provided. Rather, in cases where conflict seems to stem from the use of the word, or the use of other words, the proper reaction is to fall back on the explicit definitions, and then continue discussing the important issue from there.
