People suggest some sort of regulation for something, or some social service, often ones that are similar to those in the UK, and people who oppose it will point to things like this and use them to illustrate the slippery slope fallacy.
The US was literally the people rejecting the UK governance system and starting their own, setting it up in a way so that it would never be the UK governance system. And here you are complaining that people in the US point to government happenings in the UK as something to be wary of, saying that the US has become "governance-averse"? Seriously?
