Well, you are correct: THEY DO NOT REVERT NOR CAN THEY REVERT. I know you'd like to, but for me, I wouldn't bother wasting my time passing along expert information to some make believe expert on Facebook who would make such an ignorant claim. More often than not, they won't accept your explanation as fact anyway. To borrow a thought from a fellow forum member on here: 'There are those that want to learn---and those that never will'. Just sit back and chuckle at what they say, then smile---because you know better.
