Call me simple, but to me a “gaffe” is really nothing more than what Merriam-Webster says it is – i.e., a social or diplomatic blunder or noticeable mistake. Biden’s flub in that video certainly falls into that category. I just choose not to take it farther than that.
Fair, it is a gaffe caused by his senility and due to it being a repeated pattern makes his senility hard to deny. But sure, its a gaffe in that sense.
As for alt left, I understand that it’s aimed generically at the far (or extremist) left. I simply wondered if you had something more meaningful in mind. I personally don’t find it helpful because it can be slapped on any leftist who happens to rub someone the wrong way.
Agreed, just like the term alt-left.
