Diebert,
I see your point, but in a forum such as this, all posters should expect harsh criticisms now and again, that is the whole purpose of the forum. It prevents the forum from being too safe and friendly where people don't criticize each other because they learn to like each other through superficial interactions.
I believe it is necessary to reaffirm the forum's overall purpose, energy and scope of vision. For instance: suppose a thinker with potential came across this forum, and as they read through the posts, they noticed nothing but jokey, immature interactions of people who were always being overly friendly. The forum would be perceived as a wasteland, devoid of wisdom, no different than any other forum, but if accurate psychological criticisms and wisdom were present in many threads, it would at least show some signs of life.
I think many of the posters do not treat this as a battleground of argument, which is its entire purpose is.
Elizabeth's post reminded me of something - That you need to consciously create the environment you desire. You can't allow unconscious forces to take over, and mold it into something ugly.
While it's important not to lose awareness of the bigger canvas one is writing on, imagining some fictive audience who might get "wrong impressions" of some kind doesn't seem to be a good motivator. I think this forum has left the realms of "good impressions" for casual readers long ago. Pearls are not easy to find - it's the nature of their value.
As far as motivation goes, I'm merely trying to create the proper environment to inspire wisdom, which is one of the sole purposes for being here. And even if there isn't any new individuals here who have an authentic interest in the values of the sage, I believe that harsh criticisms will perhaps cause them to take their superficial behavior elsewhere if they are not capable of change.
You said you would constantly ban people, well, how is that any different than my harsh attacks which are aimed at either jolting someone to change or leave? both are attacks.
It hurts the ego just as much to be banned from a forum because they are deemed not intelligent enough, as it is to be harshly criticized.
