For those who don’t find “far-right” to be an applicable descriptor with what is known currently, I acknowledge that the meme creator could have been more precise with their word choice. However, I feel the difference is academic:
We can replace “far right” with the easily verified “not leftist” without changing the meme whatsoever, primarily because the meme is about Nancy Mace and her mercurial, disingenuous opinion, not (directly) about the shooter.
Edit - I modified it, though I still find it to be a distinction without a difference - alt version for those who prefer (whoops missed one first time)
Nothing is proven yet for anything, even that he was the shooter.
That said - these are all very specific references for a very specific community, even down to his Halloween costumes.
I’d be absolutely shocked if he held any belief that hinted toward the actual left.
