I wasn't a big Tony Allen fan because he SUCKED.
And yeah, the guy played basketball like a low confidence, low IQ moron. He's gotten himself into enough trouble where it's obvious that he doesn't think things through. Plus, the times I've heard him give interviews, he hasn't sounded that bright. Not based on the WAY he said things but simply on the content of his answers.
So in summary I dislike Tony Allen because he was a bad player, an idiot, and frankly not that charismatic (sometimes you've gotta factor in a player's personality. hence, my love of rasheed despite how bad he sucked while playing for us). I think it's safe to say that the majority of Celtics players disliked him for the same reasons.
But disliking him because he's "too black"? It's just kind of unreal you'd even think that.
You seem to be ignoring the far likelier answer that people just dislike Tony for all his negative traits, which happen to be numerous. If you want to call the culmination of Tony's negative traits "acting black" and then declare that people hate him for "acting black" then I suppose that's your prerogative, but it still doesn't change the fact that nobody here actually dislikes him because of his cultural background.
