I don't personally demean people and I don't tell them to F-off--maybe in specific circumstances that get to the heated exchange state, but certainly not in blanket opinion posts. And I make sure my aim is specified--those people who have a long list of WIPs in their signatures with abolutely nothing completed or even close to submission, and who complain (or brag about) how they juggle multiple projects all of the time. That doesn't stop people from getting upset about the "tone of the post" regardless of what is actually said. I firmly believe that if people don't finish their projects, they are not going to get anywhere in this business. How dare I use that tone in my posts? I must be an internet troll, an egotistical snob, or a fill-in-the-blank jerk. Never mind that the comments come from experience in the business and even more experience in a business where self-discipline is one of the most important and one of the most essential traits (independent research and its graduate training). Some of those who ignore the message and complain about the tone are doilie-dermis individuals who only want to hear writers' opinions about faerie wings, tulip filled alpine meadows, and how those pixie-ish muses just won't let them do this or that in their writing. In my opinion, these people need to be grabbed by the shoulders and given a nasty shaking. That said, I certainly don't come around here to pump my ego, and posting on my writing-related and training-related experiences doesn't have anything to do with ego. This isn't a kumbaya business, it's the most brutal what--have-you-done-lately kind of endeavor, so I'm not about to give the "there-there" head pats. And I did recognize the flavor of the thead in question and decided to stay out because even though the participants want to accomplish some mutual butt kicking, they want to do it wearing fuzzy slippers, which in my opinion, is about as drastic as trying to improve college study habits by having an Animal House style pillow fight.
And all you have to do is look upstream at one of the posts a few after my first one to see the kind of reaction I get, even though in this thread I DID consider the audience and avoided posting in the fuzzy-slipper thread.
