Does

From the second link:
> The only thing that characterizes a logical language, like LojbanLanguage, is that it's unambiguous from a structural standpoint. It seems that Lojban is just as expressive as any other human language, with the same capacity for overstatement, understatement, irony, metaphor, simile, pun, etc. A lot of famous works of fiction have been translated into Lojban by enthusiasts.
Your concerns have been brought up and explained in part by the two links above, and in the Wikipedia article I linked to. Allow me to quote some parts from it:
> The removal of grammatical ambiguity from modification [...] seems to heighten creative exploration of word combination. [...] Other areas of possible benefit are (surprisingly in a 'logical' language) emotional expression. Lojban has a fully developed set of metalinguistic and emotional attitude indicators that supplant much of the baggage of aspect and mood found in natural languages, but most clearly separate indicative statements from the emotional communication associated with those statements. This might lead to freer expression and consideration of ideas, since stating an idea can be distinguished from supporting that idea. The set of possible indicators is also large enough to provide specificity and clarity of emotions that is difficult in natural languages.
> The language was built to attempt to remove some limits on human thought; these limits are not understood, so that the tendency is to try to remove restrictions whenever we find the language structure gets in our way. You definitely can talk nonsense in Lojban.
Anyway, you can decide to be ambiguous if you wish to do so, it is perfectly possible. Do not worry, it will not turn our society into something similar to the movie Equilibrium. I think the word "logic" makes people jump to similar conclusions.
