Just like there is a difference in how someone handles it when they make a mistake, there is also a difference in how someone corrects mistakes made by others. Yes, incorrect information was provided, but correcting such mistakes can be done with a little more "tact" that just saying "Wrong", which comes across as rude. In my opinion, that one word caused this whole mess. Do you constantly just blurt out "Wrong!" every time someone makes a mistake in person? Maybe you do - but I would hope not. It's a rude, immature way of correcting someone. Of course someone is going to get "defensive" when you correct them that way.
I feel that @Bowtie396
did a much better job of correcting the mistake (and as you can see, his correctiion caused no issues):
"Actually 2014 & 2015 are 5 Year/100,000 Miles, 2016 on up is 5 Year/60,000 Miles."
Same exact correction, just a little more mature way of correcting the mistake.
Not to mention that posting videos like "The more you know" surely doesn't help the situation either - again, it comes across as rude. Maybe you like coming across as rude and getting into these little "scuffles" online, but it really does detract from the thread.
