Idiots and jerks are everywhere. Diving in general appeals to gear heads, over bearing, know it alls.
How many threads have we seen that started out with a brand new diver asking an elementary question only to get talked down to and bombarded with technical rabbit holes and the ramblings of "tech divers" and "instructor professionals". It's pretty sad.
Why is it sad? Because, it is a form of intimidation. Which is threatening. Which is against the TOS.
I tend to avoid the "advanced" conversations, read more than I post, help where I can, and learn who the blow hards are.
That doesn't say I never want to mix it up with some of the jerks on here... and there are a few. And yes, i've had a post or two deleted before in dealing with them. And that's ok.
