I get what you mean. But maybe he's a different kind of homer. One who doesn't unconditionally love the roster, but rather one who unconditionally cheers during games keeping his finger's crossed even for Biedrins free throws, but when it's not game time reality dictates him that he really dislikes a player or isn't convinced on his game.
His voice should be accepted as long as it's not a personal attack, even if you don't agree with the content.
That's for example how I work as a fan. And with a lower talent pool overseas, there's usually plenty to hate on most individual players
