One finds that often bullies contend they are the victims of bullying, and here we see the issue illustrated.  A bully posts harassment, and when called for harassing, contends that being confronted with their bullying, the bully claims to be a victim.  Interesting.  It is impossible to imagine such a lack of awareness, so the only logical conclusion is this is an attempt, clumsy and ill-considered, but an attempt nonetheless, to illustrate how bullies think and act.   At least one must hope that is what this fellow is doing with the constant posting of nasty comments, but perhaps he actually intends to harass?  One can only speculate...sigh...
