If that was the conversation then yes. But when the conversation is about party A fucking up then bringing party B into it is whataboutism. It’s the literal definition of a whataboutism.
The meme is about Jimmy Carter running as a candidate for election… The conversation is clearly about an election in which we are comparing candidates for an election.
This isn’t “Joe Biden makes a goddamn awful margarita.”, in which “Well putin makes a worse one” would be a whataboutism, this is “Joe Biden is too old to run as a candidate in the election”. And in an election, you compare candidates, which is not a logical fallacy.
And we’re talking about Jimmy Carter because we’re talking about replacing Biden. Telling people to shut up, Trump is worse, is a counter accusation without basis in that context.
Ah, so the idea is that candidates for the position are not yet locked in, therefore comparison between party candidates is not valid. I can get behind that.
However in the current environment I don’t see many other paths forward. I think the best alternative I’ve seen was an article floating al franken. My guess is the original commenters worry is that without viable alternatives, it will likely become a Biden vs trump election, and by then we’ve provided ourselves with enough negativity against Biden to encourage a trump victory. I’d like to see more positive qualities of alternatives be brought up, instead of negatives about the current most likely nominee.
