Point by point.
How does expressing your views preclude responses? That is a non sequitur.
People posting not using their real name is irritating and to my mind less than candid. I sometimes put much less consideration into the posts with pseudonyms. I have yet to put my finger on that Constitutional principle that shelters me from being irked.
But many are thoughtful and enlightening. The Federalist Papers and the Anti Federalist Papers in which the founding of this nation were debated were in fact published anonymously. Do they merit similar contempt?
How does your choosing not to respond to comments preclude your allowing comments? You don’t have to respond. That is your prerogative.
The reason I allow comments is that I want to hear what people think. I respond selectively. I would rather give each the opportunity to express their thoughts. For me each comment stands on its own merits. Let the reader decide, not me.
The fact that there are other channels with which to communicate with you so you do not allow comments again is a non sequitur. One does not preclude the other.
I do not consider myself to be an elite who is above the great unwashed. I proudly wear the contempt of those who would deny others the opportunity to respond.
