Quite difficult to file a lawsuit from a prison in El Salvador.

It ain't no cakewalk from a torture prison in Sudan either.

Before today’s ruling nationwide injunctions were granted. Not sure how you can now claim “that’s how the court system works” when nationwide injunctions were fine before today’s ruling.

A President can now issue blatantly unconstitutional executive orders and the burden for obtaining relief will rest on each individual person (or small class of people). Prior to today rules/laws that caused harm could be temporarily prevented from being enforced while the matter is litigated. Now parties that will be harmed are much more likely to be harmed before the matter is resolved. This is a sad state of affairs.

If the next President issues an order confiscating guns from people the champions of today’s ruling will want nationwide relief while the matter is litigated.

If someone is going to be deported they can file a case and stop the deportation.

And you accuse OP of not paying attention!

Also, just because you did pay attention doesn’t mean it’s not idiotic. The patchwork of interpretations and requirement to sue is a guarantee of unequal treatment under the law, which is exactly what autocrats want.
