When I don't agree with anyone or someone, I still look to see what it is that we have in common, and, to be mindful of our own self centered ideas that come from a lack of effective learning from others.
That means, we all have an obligation, to bear in mind our own bias and to refer to the subject or the content of the post and not the person.
When readers start attacking the person, the character and reputation, to me, its ample evidence that the post has crossed the line as in this case, the subject is the abuse of power in banning "The Colonel" for his opinions.
I trust that every pilot sits on his butt when flying or otherwise engaged, possesses a rectum which, like opinions, is something we are all entitled to no matter how much others may not wish to look at.
