When anger and resentment go too far: film critic bans commenter for salacious remark about the former's personal life.

Precis of the events you will read about below:
LexG is a gadfly (working in the post-production part of the film Industry) who posts to a lot of film blogs (including Jeffrey Wells' HOLLYWOOD ELSEWHERE--where I post as well).  Lex has a horndog persona (in LexG world, Megan Fox and Kristen Stewart are the Ultimate Women)--occasionally, he'll say something fairly interesting and cogent.  But he's an acquired taste for most.
Glenn Kenny used to be a film critic for PREMIERE magazine; now his reviews can be read on MSN.com.  Glenn has a blog called SOME CAME RUNNING, where Lex was a commenter until recently.
Two years ago, Glenn played a small and memorable role as an adult-film critic in Steven Soderbergh's THE GIRLFRIEND EXPERIENCE, which starred adult-film actress Sasha Grey.  In a fit of lack-of-manners, Lex wrote a somewhat offensive remark regarding Glenn (and somehow relating to Ms. Grey), which I won't quote here.  Lex's banishment came afterwards.
