When I'm handed a loaded question, my first reaction is to see if I can unloaded it, disassemble it, and hand it back in pieces, without pulling the trigger. If you don't want that done with them, don't hand them to me.
Loaded questions are designed to trick people. What do you think I'm trying to trick you into when I ask if these folks appear to be into scientism?
Your position appears to be that if something looks like a duck, walks like a duck and quacks like a duck, it's not a duck. Plenty of tactics, not much logic.
Speaking of ducks, it appears that this...
...is your current position. Of course, if I was advancing the idea that it's unwarranted to call Weinberg a follower of scientism, I'd be a little nervous, too.
