Based on my experience, “disagreeing with wingnuts” is a crime in the U.S. 
If one is a big enough source of embarrassment there absolutely WILL be some sort of effort to criminalize something that you did. Look at what’s happening to Hunter Biden - a fool with a drug problem, but nobody else is being prosecuted for the sorts of things he did.
So … not everyone who worries about 4th Amendment issues and Qubes is a criminal, but we all need to proceed from a worst case estimate.
