How white are you, out of curiosity? What's your demographic look like, and how closely did it match the screeners? Seems like if you were nervous that would be additional weighting in the direction of you being questioned, so the additional weighting doesn't seem to have motivated anything.
It was tucked into a backpack along with quite a few other things (including 2 soldering irons, actually). I don't remember exactly what else was in the bag as to whether there was anything that could have looked like fuel in the scanner though, so fair point potentially. However, while it wasn't the point of my anecdote, I'm also fairly confident being white was one of the factors that played into zero questions being asked.
I am white male, and it was in a Southern US airport that was also very white. While that wasn't the point of the anecdote, I'm also fairly confident it played a large part in there being zero follow-up questions.
