I think, given the sort of intense "loyalty" that certain members of the sparrabeth community have displayed over the last few months, you are either stuck with disabling anonymous comments (which is the easiest and, frankly, because I hate the anonymity of hate, my preferred solution) or just ignoring the trolls who post here. I think asking for respect is like farting in a windstorm. The people who are going to be respectful don't need to be told and the people who are NOT, could care less. IMO.
