If I am on an "anonymous chat forum" it is a particular and special social activity that is "anonymous" as an agreed condition for all parties who engage in this "anonymous chat forum" activity and indeed anonymity is part of the agreed on terms and conditions...
It is equivalent to conducting an activity in the privacy of my own home and thus as I stated, I could freely wear a burka if I chose to while conducting this "anonymous" activity and I would not care if you decided to keep your burka on during this "anonymous chat forum" activity...
Of course only a complete idiot would actually chose to wear a burka and so it is merely hypothetical...
