Its something and nothing at the same time. It is yet another demonstration that the fed government doesn't want/can't govern, and it is a constitutional crisis. But the actors involved are only pushing this for pandering/grandstanding for electoral ends. They aren't pushing this to actually secceed or push any political agenda beyond elections. That's what makes it nothing.

Its the same way Jan 6 was nothing because even though it was inserectionist the peoppe there had no clue what they were doing beyond the spectacle of it and what they were doing was never going to matter beyond spectacle.

I agree that the implications are down the line. That's how cynical pandering to the chud base has always worked. Its hard to say when any of this will lead to an actual "something" though. Eventually yeah the chuds aren't going to be happy until they order the national guard to open fire on the feds, but at that point even the base is still only politically engaged in that spectacle and not its implications. That's why people at Jan 6th thought they could just fly home like nothing happened, because they are completely detached and unaware of the implications.

it means that mayobrained right-wingers perceive the racist violent federal border agents as "not being racist and violent enough"

They're stepping in to do the work for free, and the feds look at it and shrug their shoulders and think "eh sure why not"

Wishful thinking I’m afraid

If they were to allow Texas to do anything it wanted then sure, you'd be right. Some governors saying they side with Texas against the Supreme Court (when they aren't technically violating what they've said yet) doesn't mean anything.

The Supreme Court says the federal government can cut through the razorwire to reach where they need to reach. It doesn't say Texas can't put razorwire up, so they haven't violated that. It's 100% nothing for now. If Texas decides it wants to turn it into something and stop the federal agents from doing their job, then it becomes something.
