Question two is a totally different topic and I suspect the real point of this thread. I believe ethical isn't the proper word choice. Ethics has nothing to do with somebody editing your post if they in fact own the site on which it is you are referring. Something tells me that there is much more to this question/story that we aren't hearing. So what is it that wingnut did this time ?
You can probably get a better more succinct answer from living Trail Poets like L. Wolf but dead philosophers provide some food for thought.
Maybe the question should be: "Is it ethical to start a thread that is a personal rant disguised as a legitimate question? Sounds kind of childish to me.
