Is expressing that opinion so wrong?
When you do so anonymously, yes! Your opinion of my or Liz's or anyone else's physical qualities is not really of any interest to any of us and to be honest (ever heard of that word?) I would be too polite (or is it disinterested) to comment on what I thought of you even if you were known to me (I rather hope you're not I'm choosy about the company I keep!!)
