Ignoring social norms, impulse control issues and problems with empathy.
I don't talk about stars at all, I never watch TV or listen to the radio. I talk about politics because I study it. Its kind of hard to watch as yet another retard somewhere in the media butchers the public discourse again and again without comment. Although I am trying to concentrate on philosophy more.
Besides, if you don't like what is being talked about, perhaps you should start some threads on what you like? Just a suggestion.
