ok not even touching on the substance of the post (pretending to be black online is cringey and stupid; using a reaction gif with will smith in it is not the same), but you cannot claim you've done research or that you know shit if you're claiming blackface "stems from Jim Crow Laws." or "Jim Crow is the man who created blackface"?! is this a parody?
ok, to be clear, "blackface" is two things and people use them interchangeably, which muddles the water. first, it is the practice of an actor or performer
darkening their skin in order to play a character, such as
Othello, which was
theoretically done "respectfully"; second it is
specific performance
trope associated with
minstrel shows and the specific 19th century trope/archetype/stereotype
of the "
darky," which, like "
mammy" and "
pickaninny," stem from an
antebellum and, obviously,
deeply racist set of imagery and (comic) ideas about black people--namely, that they were big, ugly, goofy, slow, dumb, musical, cheerful, stupid, and inherently a joke. the first kind of blackface is
bad; the second is also very, very bad but stems from a specific (and Jim Crow related) tradition of
American racist iconography/tradition.
blackface as a theatrical convention (type 1) is
older than the USA, but the "traditional," widely popular blackface in the USA (type 2) came out of
minstrel shows, which had their heyday in the 1820s-40s (but, to be clear, continued long after). blackface as a trope
continued into the 20th century (a shockingly long time,
actually), but its
roots are in the 19th.
Jim Crow Laws, by contrast, colloquially describe a series of laws implemented in the late 19th century in the wake (read: collapse/failure of)
Reconstruction. the
name "Jim Crow"
does come from
an incredibly popular 1828 minstrel show featuring blackface, to be fair to this person, but there
was no Jim Crow, he did not "create" blackface, and the laws nicknamed for him came about decades after blackface-minstrel show comedy had come into its own.
I don't know how someone can claim to have done research on a topic and make sure a blatantly false claim about the nature of the thing they're discussing.
tldr: minstrel show blackface as a mainstream cultural phenomenon was popularized by a character named Jim Crow decades before the laws called Jim Crow Laws came into being; blackface does not stem from Jim Crow laws.
