> You can write a reply and then erase it without sending, and that's the best thing to do in most cases. Sometimes I do this, but more commonly I will write my comment and then just not check that discussion ever again. I only check the discussion if it's a situation where I am willing to engage if there is a response. My experience has been that replies to any comment that's even mildly controversial are such that the other party will not bother trying to understand what I'm saying. In many cases I might be posting a piece of data (with a link to the source) and inevitably someone's going be upset because they don't like the data.
