That’s not a useful definition in a democracy. Who gets to define what’s justified if not the duly elected legislature? I bet if you put the current Texas law on the ballot today you’d get the same answer.
If you put that on the ballot in other states this would be more popular than initially thought by most.
It is a useful definition, because it allows you to talk about places where the law might be unjust.
You can't have a functioning democracy if it's impossible to criticise the current setup. This is the whole idea behind newspeak [1]
