GW258 - cactiboss did indeed, publicly slander another pilot, in my opinion. After I read his post I was reminded of the seven types of lies.
One type-
'"Potential Truths – Saying something as if it were fact without knowing for sure that it is true is also a lie. Fabrication is also included in this category. Rather than something that is just pulled out of the air, it could also be a misinterpretation of information or drawing false conclusions. Like explaining a scientific concept without actually knowing the fundamental principles and making it seem like you know what you are talking about or telling someone who asked for directions the way to someplace when you don’t actually know where it is."

This behavior is particularly reprehensible in light of the post that has thankfully, been since removed.
