I would rather this thread not fall into being political -- we should start another thread for political discussion if so desired -- but I will just say I'm still not clear on what "conservatism" means, or what the "good" version is that people insist the modern American right-wing does not represent.

**It's 2021 now and I hate everything I've said in this thread.**

Interesting, although any language is going to be full of these, due in great part to the inate laziness of speakers and the inevitability of omitted words. In fact, the second meaning you prescribe to your example is actually derived from omitted words and isn't accurate (the full sentence being something like "which relatives do you want to have visit?"). It's a contracted sentence that could mean the same but really just reflects poor grammar. The reason why when wanna is used, the meaning is clearer, is that it is a contraction of the original meaning, and is not also a contraction of the secondary meaning (which as above is a misreading).

Much of language works on subtle clues here and there, and regardless of the isolation of a spoken or written statement, there would always be a context that would lead us to read or hear a certain meaning. Indeed, I would argue that it's impossible to not have context of some kind.
