Creator of the top definition here. Wanted to try and clarify my older definition now that it's been mulling over for everyone a while now, and clear up some misunderstandings. So here we go.

The Left Can't Meme is indeed an immutable fact. But why does it occur? Well the statement has never been an attempt to 'politicize meme culture' as some, left leaning or otherwise, try to posit. It is in fact the opposite. The Left Can't Meme is rather an attempt to POINT OUT the needless politicizing of memes, it being done the majority of the time by left leaning people. The Left Can't Meme as a statement, as a law, has never been about making the case of memes needing to be 'The Left vs The Right', it has always been a defiant declaration of 'The Left vs Everybody, including normal leftists who just want to look at memes'. Do cringy, politically-charged, righteously indignant memes come from people other than Leftists? Yes of course, but the vast, VAST majority of the time when there's a meme that looks like something straight out of a politician's propaganda folder, it's a Leftist who made it. The problem with this law is that it simply will never stop being true, because there will always be people who see memes as a platform for their own righteous indignance, rather than the symbol of humour they were meant to be.

The only thing to be done is for normal people with a sense of humour to point out these political memes and denounce them for what they are: Cringe.
