Accepted by whom? All of the examples on my list are socially accepted by different groups as either activities themselves or at least as spectacles. Hunting is accepted as both activity or as a spectacle, while other forms of violence are accepted at least as a spectacle - just check the lyrics of rap, hip-hop, or punk songs.
Lest you miss my point altogether - this was my tongue-in-cheek response to some previous comments that celebrity watching is just fun. By the same logic, we can "explain" any behavior as "just fan" without saying anything about the actual cognitive processes underlying that behavior. We can equally "explain" that behavior by saying that people "chose" or "prefer" to do it, some prefer to be poor, other prefer to be rich, and still other to prefer to have fun. Got it?
