Too many self opinionated willy waivers simply turn off the average flyer from posting anything!
It is a reasonably common theme in this thread.
Let me offer this.
Flying will in part attract pilots with strong personalities. After all private pilots are often financially successful people that are well motivated (note the use of often, not always).
Moreover what is the point of a debate unless contributors are forthright and have convinction about their posts.
However you are right some posts cross the line and are vexatious or ill informed.
I wonder what others think?
