Someone far more wise than me, I think it may have been Dan John but not sure, said something like "before the 70's, Fat was just the juicy bits on meat".
WHen i lived with my parents I had similar problems. They looked at me like I was taking steriods when I mixed up a shake. I actually 'smuggled' my shaker etc to my room to take my pre bed shake because they thought it was really bad to eat late at night - if I ate at 9-10pm I would get lectured.
Any time I got ill - maybe once a year - It would be "all those chemicals you're putting in your body". (meaning the protein shakes)
I would buy my own eggs so they couldn't track how many eggs I was eating because, you know, more than 3 eggs per week and your arteries will simply explode.
No chance in hell would I have shown them Creatine. They probably would of thrown me out the house.
It's just part of the joys of separating yourself from the average. Typically, the more criticism and general

you provoke from people who don't train, the better you're probably doing.

I have a similar experience with my friends and family as well. When I was using creatine way back in the day, I was "roiding up". Then I got really upset at something stupid one time and my family was convinced I was on steroids, even though I wasn't doing the stereotypical roid rage breaking anything or beating on people, I was just yelling. God forbid I just get mad about something. Anytime I tell anyone I know about my low carbism (which was really eliminating sugars and white flour) I'd get a lecture, and so on.
