I have complete sympathy with OP. I used to be the one in the office that had a basic knowledge of computers and everyone else would come to me for the most inane issues and to do the simplest things.
So I know how to write formulas in Excel, I know how to format a doc so it looks good rather than the mixed sized, confused layout and general mess that they would create, I understood how to use very VERY basic HTML in e-shot emails we would send to clients... and when I left the company the boss actually said I should get a job 'in computers'.
The problem was not the lack of my colleague's technical knowledge but rather, their complete inability to learn and re-apply new information. These weren't middle aged or elderly people afraid of technology, these were a group of people that struggled even if the company introduced a new admin process (and usually just gave up and did it the old way anyway... causing problems that someone more competent had to sort out).
...and you're right OP... if you point them in the direction of the answer rather than just wiping their backside like you're their Mammy, forcing them, God forbid, to use their brain... they look at you as if you'd just spat on their Grandmother and proclaimed their first born the Anti-Christ....
