This article explains that “the Fourth of July” is was in use (scarcely) towards the end of the 18th century, HOWEVER I still think liberals make a concerted effort to suck the meaning out of it:
What I’m saying is this: Facebook has a choice. They can use “Independence Day” in their stupid posts, but they don’t. And I think it’s deliberate.
Facebook, and much of the media, want us to be part of a ridiculous “global community”. We’re therefore not as “independent” as some would like to believe.
Just my take on it.. and yeah, I think its nefarious.
