The notion that ‘meme’ is a meme, is a meme. It’s memes all the way down.
If I had a pound for every time someone said that…
First thing I thought of from the title…
WWJD?
Really?
For the most part, yes. Hinduism and Buddhism most definitely predate Islam and Christianity by at least a couple of centuries if not millennium. But in regards to Judaism I’m honestly not too sure, its pretty tricky to track down its beginnings as a religion.
Judaism is definitely part of the Abrahamic religion(here’s a hint-it’s come from “Abraham”)-so…no.
I know that Judaism is part of the Abrahamic faiths. I should of worded it better, what i was trying to say is that its not as easy to work out when Judaism began but it is for Islam and Christianity.
So when you were comparing the ages of Hinduism, Buddhism and the Abrahamic religion, you actually meant Islam and Christianity?
Edited to add: BTW, Islam is an Abrahamic religion.
Christianity is an older religion that Islam: Muhammad (c. 570 – June 8, 632).
FFS! I was saying that both Hinduism and Buddhism were much older than Christianity and Islam, but i wasn’t sure how old Judaism is. That’s it.
When do you think Hinduism and Buddhism began?
I haven’t attended a regular church service (other than weddings or funerals) in more then 30 years, but back in the 1970s there was a push to include modern music to the standard hymnal. This was the United Methodists who were rather liberal for that time period. I suppose that since Christian Rock is now an established genre then this wasn’t a fad.
How about Marriage Encounter? I see from a Google search that it still exists, so I suppose it is not a fad either. Hmmmm… I appear to be hopelessly out-of-date as to the current state of affairs in churches these days. Perhaps I should consider myself ‘blessed’. 
Buddhism began roughly 500BCE, half a millennium before Christianity and over a millennium before Islam. Hinduism in one form or another has existed for somewhere between 2500 years and nearly 4000 years.
Among these(Islam, Christianity, Buddhism, Hinduism and Judaism) which would you consider to be fads?
Well one way or another I would say all of them, but the Abrahamic ones more so.
One thing not mentioned that Christianity had (and still has) for various reasons a strong appeal to the poor and oppressed. A population pool that never diminishes.
The word ‘fad’ has a connotation of aimless frivolity that is markedly lacking in religions. Thus I conclude the OP premise is simply another SD dig at faith. About as nuanced as Four Legs Good, Two Legs Bad.
Hinduism predates Judaism by perhaps a thousand years. Buddhism predates Christianity by about 550 years. So?
The point is that because religions are always being created by people they come and go, but not as quickly as things normally associated as being fads.
It isn’t a dig its simply an observation Sherlock.
I was answering someones question.
Fad:
Something that lasts hundreds or thousands of years cannot by any stretch of the imagination be called a “fad”.
OK, if we expand our set of religions to include those created in the last 150 years or so, we have Neopaganism, Wicca, The Church of the SubGenius, Pastafarianism, Discordianism, and the Cult of the Invisible Pink Unicorn. I am certain I missed some in there. The first two are somewhat ‘serious’ religions in that their membership actually consider the religion to be their chosen path of spiritual life. The other four appear to be parody religions.
So, perhaps the existence of parody religions is a fad.
I have to strongly disagree with you here. Fad implies a relatively short life-span. The religions that you list are all ancient and long-lasting. Compare the length of time that people collected Pet Rocks or Mood Rings with the length of time of the youngest of the listed major global religions (Islam, I believe). This is not a mere quantitative difference but a qualitative difference. Fads are not typically passed down from one generation to another. Religions are and therefore are long-lasting both in their existence and also their impact of the associated societies.
