If you classify people who are not Muslim, Jewish of Christian as pagan, then that includes atheists. It's just my pedantry showing. And on your qualification of your classification, where are you putting Buddhists?
Whether Sriram is a Sikh or Hindu is surely irrelevant, by your classification, he's pagan and I suspect by JCs.
I am sure that you wouldn't classify Gabriella's as a pagan but I am guessing by JCs view which is what we are talking about, she is.
You keep your pedantry and I will keep my lack of it.
I have said, and I stand by it, that I consider ONLY religions that existed at the inception of Christianity to be classified as pagan., but this is, in the end, only my definition.
If religions that have come into being since Christianity's incept choose to define themselves as pagan religions then that is their choice, but I have yet to see any post-chritianity's inception religion that has so defined themselves.
Atheism is not, so far as I am aware, a religion and, even if it were, it cannot claim to be pagan by my definition stated above - what you call it is up to you.

Is it a religion?
It is neither a religion in the sense in which that word is commonly understood, for it is not "a system of faith and worship owing any allegiance to a supernatural being."
This article is well worth a serious read.
Therefore 'no' Buddhism is not a pagan religion or any other religious classification.
I would say however that, as practices in Australia, Buddyism is very definitely a religion, a religion whose God is BEER! Beer in any shape or form but preferrably lager and in abso-bloody-lutely vast quantities. It is, in all probablily, the most ardently followed religion anywhere in the world.
