I saw the post you reblogged about the LLL thing and La la land and, according to urban dictionary, it stands for "loony liberal left" which is probably exactly what the joke is about, because celebrating a movie about black music which is all about white people is the exact kinda thing that liberals tend to be known for :P I don't think that's illogical but it's obviously an in-joke, and in-jokes often confuse people in the out-group, unsurprisingly. That's the nature of them :P
I completely forgot to respond to this, but thanks for the clear up!
