Ok, if you want to get personal then perhaps personal messaging may suit better.
(Strange how you would know that I would not fit in.)
Mr Helmick I have given you a couple of days to explain yourself privately about an unwarranted personal attack on myself and yet there is nothing, so public it is then.
You claim that "I only come here to be argumentative, often about engineering minutia," that....... is far from the truth.
If you care to survey the number of views compared to the number of replies on ANY forum worldwide you will find that the views outnumber all else, and I am no different or special to any other member here.
I view FAR more that what I reply to and yes, "engineering minutia" is a passion of mine so I look, read, form an opinion and if I feel qualified enough I jump in and reply.
And in keeping within the personal vein that seems dear to you, I am a moderator on another site about model aircraft engine developement, so yes I have a vested interest in mechanical small talk, how posts are constructed and member behaviour. Its kinda my hobby.
I am assuming here all of this started after me asking you in the "To baffle or not to baffle" thread why the muffler on an OS LA 46 was considered to be a quarter wave device?
I gave you the reasons why I considered it not to be (quite extensive reasons too) and again you had no reply probably considering this to be an attack on what you thought to be the truth hence it must be a personal one too.
And yet I have never said anyone was wrong, never said well you wont fit in to any group with an attitude like that or went straight to using the formal term of Mr which (again assuming) can be taken as derogatory.
The point with displaying signatures, ranking, icons, post counts or whatever embroidery surrounds the written text is that it detracts from the meaning in an attempt to bolster the author through artifical means, and its repeated and normally unsolicited.
Hence the original question of how much is enough? How much is tolerated before someone says something? What amount is considered abuse?
I gave my opinion as a start point and hoped others would give theirs too and it devolves into this?
P.S. In regards to not 'fitting in' my attitude here fits well enough as a forum moderator as mentioned and at times on forums but I do not use that attitude on a flying field, why would I? Few flyers talk forums outside of a keyboard so it would be futile, wouldn't you agree?
