I think another way to say this is that some people see laws as one layer in a stack of principles of varying degrees of generality, and believe that it makes sense to oppose a policy at more specific layer if it conflicts with a more basic principle at a deeper layer. Others see laws as just arbitrary dictates: you follow the law or you don't, and that's it, the law doesn't represent or instantiate any principles or ideals, it just is what it is.

I'm not sure the distinction here maps cleanly onto a left/right political axis though. People on the right also think that stuff like refusing to serve gay people or (at least in the past) standing in a schoolhouse door to block racial integration constitutes a form of legitimate resistance or protest against unjust laws. And there are certainly those on the right who believe that certain acts are okay (or more okay) when done by certain people (e.g., the homeless, oppressed racial/ethnic groups).

It does seem to just come down to different views of what principles are in that stack and what the priority ranking is. An obvious case is that many on the right would give certain tenets a central, foundational status on religious grounds, whereas it's increasingly the case on the left that religion isn't considered a legitimate basis for public policy. And in fact, the divide is even deeper, since many on the left consider that secular perspective itself central and foundational --- one side thinks certain things should be illegal because religion says so, while the other side considers it wrong for the law to even take account of what religion says.

In light of this what I find frustrating is that so many of those on the left (especially those holding political office) are unwilling to turn against those institutions themselves on the same grounds, namely that the institutions are subverting and impeding more basic ideals of freedom and justice. Democratic politicians shouldn't be arguing about this or that Supreme Court decision or what this or that Senator did or didn't do; they should be arguing that the Supreme Court and the US Senate are undemocratic institutions and should be swept away entirely, along with a good bit of other governmental cruft, in the furtherance of the root goals of democracy and equality.
