Who gets to determine which religions are "real religions"?
I do, of course, or any sensible person.
Some real religions:
Buddhism,
Christianity,
Confucianism,
Hinduism,
Jainism,
Judaism,
Shinto,
Sikhism,
Taoism, and
Zoroastrianism.
Some fake religions:
Jedi,
Pastafarianism,
Festivusism, and
Sith
Any sensible person can tell which list Islam belongs on.
