I like the post you pasted… 
Black VS White: Two identifiable categories whose behaviors we can monitor, measure and do something about.
Man VS woman
Again, two identifiable categories that are easily identifiable. We can in fact categorize, generalize and do something about.
LGBT - Okay we have several categories here based on sexual preference. Not as easily identifiable, probably due to the social stigma attached to many of the categories. Still, those who openly identify are easy to find, easy to find concerns, easy to identify as a self reported group.
Good VS Evil - Amorphous Bullshit about which no one has any sort of clear definition. Our little Christian sect is good and yours is bad. There isn’t a fucking thing agreed upon in this little good vs evil bullshit division. Draw your line firm in the sand? If the Christians did that, the protestants would be killing the Catholics… wait a minute… they already tried that didn’t they? Mormons and JW would be running for cover. All the religious West would be attacking Islam… Ummmm… oh… never mind…
Good vs Evil is the stupidest division any moron could ever possibly think of.
