America doesn’t work like that. Due to the way the electoral system is set up only two parties can be viable at any given time. The only time you can create a new party is in a realignment, eg. When Lincoln formed the republican party as an explicitly anti slavery northern party and the democrats became the pro slavery southern party. Prior to that it was the whigs and the democrats, which were aligned around issues other than slavery.
So unless the progressives can force a realignment along some new issue and subsume a major party, creating another party would just be handing a lot of elections over to the Republicans.
This is why lemmy was so vehemently against Jill stein and the greens even though most people on here agree with her politics more than kamala, because they saw her as sabotaging the democrats chances and handing the election to trump.
Also hijacking a party is easier than building a new one and if you gain control you can use the power of that party to shift opinion. Most voters these days vote based on there team, or more recently against the other team. So if the democratic party started pushing a green new deal then the rank and file would fall in line, if nothing just to stop the Republicans. You can see this in how trump hijacked the Republicans. If you showed a republican project 2025 in 2015 they wouldve called it absurd, but now most are in support of it.
It seems to be a bit of both. The article does cite a lot of comments agreeing with what the older relatives said and getting a bunch of likes. So some people are laughing at how horrible and racist it is, but some are laughing at the unapologetically saying what we’re all thinking aspect.
A lot of racist jokes are just people saying their biases out loud and unapologetically, and then the racists laugh because they agree, and they get to affirm those beliefs. You might get some people on the other side laughing at the absurdity, but for the people of the race being made fun of, it just feels like the attack it is. Especially when the subject is serious and you can’t distance yourself from it, and nothing is more serious than genocide.
Like if you showed these to a Palestinian child they’d probably become depressed and scared by it. If you showed these to a boomer israeli they would probably laugh at it and say they’re right.
