I don't know that I'd go so far. As suggested by its original name, Loglan, Lojban was created as a Gedankenexperiment: Could human beings learn and use a language whose grammar was based on that of formal logic? So I don't see it particularly reactionary--or, when it comes right down to it, as an auxlang in the same manner as Ido, Interlingua, or similar attempts.

What other ones do you have in mind? I think much of the appeal of Klingon stems from it being an artlang with very un-SAE grammar that is nevertheless not as difficult to learn as the natlangs it was inspired by.
