Learning QM has been compared to learning to ride a bicycle. You don’t do that by first defining your terms, you just get out there and do it, and it’s hard to reduce the knowledge of how to ride a bike to definitions.
This may indeed be the case, but taking the outside view—if I didn’t know you were talking about QM, but knew it was about some purported scientific theory—giving a free pass to the usual strict rationalist requirement to “define your terms clearly” would seem pretty dubious. There are a lot of ways to build whole systems out of equivocations and other such semantic fudging, a lot of religious argument operates that way, and so on.
