I've unabashedly stated it before and I'll do so again --- the one primary cause of man's inability to make any significant headway towards a peaceful planet for all is fundamentalist religious insanity.
The United States is not immune to this insidious disease. Case in point:
An evangelical Christian hate group called “Repent Amarillo” is reportedly terrorizing the town of Amarillo, Texas. Repent fashions itself as a sort of militia and targets a wide range of community members they deem offensive to their theology: gays, liberal Christians, Muslims, environmentalists, breast cancer events that do not highlight abortion, Halloween, “spring break events,” and pornography shops. On its website, Repent has posted a “Warfare Map” of its enemies in town.
I truly wish this were parody, but it isn't. It's my hope that at some point, decent Christians will find the will and courage to stand up as a group and denounce these fucking hateful lunatics, do so loudly and forcefully, and shame them all back under the slimy rocks whence they emerged.
