What Characteristics Tend to Make a Religion Lame?

Certain atheists seem to hold that all religions are equally lame. I tend to think, however, that some religions (e.g., Scientology) are lamer than others (e.g., Quakerism).

Here are characteristics that I think will tend to make a religion that possesses them lame (and the more it possesses, the lamer it is):

- requiring its adherents to pay money in order to learn whatever "truths" the religion has to offer (Scientology)

- there's good historical evidence that it was founded by a con-artist (L. Ron Hubbard, Joseph Smith).

- encouraging its adherents to commit suicide (Heaven's Gate, the Peoples Temple of Jim Jones)

- rigid adherence to readily falsifiable claims about reality (YEC, Scientology)

- harassing non-believers, critics, and apostates (Scientology, Roman Catholicism in the past, LDS in the past, Islam, some Protestant sects, many others)

- positing a detailed scheme of supernatural beings (LDS, Roman Catholicism, Hinduism)

- promoting or winking at vulgar superstition (Roman Catholicism, Islam, Santeria, Hinduism, LDS)

- discouraging members from associating with non-members (Jehovah's Witnesses, evangelical Christians, Islam)

That's my shot at an initial list. (NOTE: My initial list has been edited to reflect comments from others.) I'm sure this could be enlarged and refined. Also, needless to say, the examples in parentheses are not meant to be exhaustive.
