What is that URSF and how does it defeat bikechain? I really want to know. Bellow is my confused thought.

Discussion
URSF nodes present a simple threat to miners: "Hey thats a nice block you just made there. Must have cost you a lot of money to make it. Be a real shame if I just fucking rejected it."
Is it "User Reject Soft Fork"?
It sounds another softfork from old chain and hardfork from miner driven softforked chain.
Am I understanding correctly?
It is basically saying that any blocks signaling for drivechains activation will be rejected by nodes as invalid. If there is a significant adoption of URSF by ecnomically important nodes, the miners won't even bother.
It is hardfork, right?
No it is a constriction of the existing rules for acceptable blocks.
Then the other softfork(maybe miner driven softfork) becomes hardfork. It seems that the term is not that critical.
Thank you.
Two soft forks in disagreement does not equal one hard fork. The rejecting node rejects, and the activating node signals/accepts. All actors take risk in being on the wrong side of a reorg, but the miners have to choose especially carefully, because they have risked their income.
Node runners have already proven that they are willing to threaten network instability in the face of consensus changes that were foisted on them through miner politicking.
As far as I know, Segwit UASF disagree with hardfork and agree with softfork.
However, what makes me confused is how to say NO through a node to miner driven softfork.
