I'm a fellow empathy challenged sadist, and have found your blog to be both entertaining, and informative. I'm not sure what my proper label is, but I don't think that matters so much as something else, getting rid of this damn stigma.
I guess that although we share similarities in that which we crave and indulge upon at the cost of others, I think I might be some weird off-beat do-gooder. I do mean do-gooder, too, not good.
In some strange sense, I think that we as emotionally challenged individuals have the rare gift of emotional detachment to the social themes of Good and Evil, and in this, when we commit an act of Good, we're in fact doing something more profound than say, someone compelled into being good through morals, social norms or emotions. There's no guilt or shame factored into our actions, in general, so when we decide to not be a self-centered bastard for a moment, and help someone or something out, it should mean something more, especially since we tend to gravitate towards the easier choices that best serve us.
We get a bad rap for only doing good things that benefit us somehow. So what? If an empath's claim to fame in the society-perpetuated Holy War raging between Good and Evil is that they feel that they need to be good, then who is being the bigger hypocrite? Are our actions not in some twisted way more genuine than theirs? At least ours are our own, not affected and forced upon us by some strange, emotional pull or man-made moral code.
A lot of people don't seem to realize that there's more empathy challenged people on the other side of the prison bars than what the media and probably a fair amount of self-righteous crusaders would like the masses to believe.
So, because of this, I've taken it upon myself to help add to our community with my own blog, to erect a banner that proudly displays that yeah, we might be inter-species predators, but we're not all a bunch of loony criminals that eat people and kill dogs for kicks. This is who we are, love it or hate it, you silly, irrational empaths. We're everywhere, and although you're easy prey, you're not all on the menu, and even if you were, it doesn't mean we're interested in specifically you.
