Christianity - the lifestyle choice that elevates one to a position from where you can look down on everyone else, and point out their mistakes - and everyone who disagrees is automatically "evil", "anti-God" and a "heretic", a "deviant" - or a threat to "the family", and somehow less of a human being for it.
This is how a friend of mine put it: "Very true - even of "good" Christians who claim to hate the sin but love the "sinner". "No, you're not evil, but your acts are evil." Evil. Good. Evil. Good. When will people just be able to accept reality as it truly is?"
When people stop fearing the dark as some representation of evil and see it as a shadow, an absence of light, and also a consequence of it.
