No need to leave RE, your points are as valid as anyone else's. In any case not liking Omar, on the face of it, is just that - not liking Omar. It's not obligatory to like any individual and, on its own, shouldn't be taken as indicative of anything else.
I think, judging from articles in the press and also from what some of the other individuals involved have said, it's fair to conclude that, despite the perceived persona given to others [including me] Omar hasn't exactly gone out on any kind of charm offensive in his dealings with people.
All that said, RW's post [if indeed it was his] is potential dynamite and can't realistically be ignored by those in charge of the game; the boil must be either proved to be an illusion or be lanced. We live in interesting times.
