Buddhism is certainly an organised religion in Sri Lanka
When i said Buddhism is not a religion what i meant was that it was not Buddha's intention to make his teachings to be followed as a religion.
The present day Buddhists have turned his teachings into a religion. therefor i guess you are right. Buddhism is a religion. but that was not Buddha's intention.
His teachings were a way of life to achieve NIRVANA. He did not say that if you do not follow his teaching that you would BURN IN HELL.
But he did say that his teachings were the ultimate path to NIRVANA(enlightenment).
But he also said that YOU (anyone) could on their own could find the path to ENLIGHTENMENT.
Yes, it is, and has been for a very long time. Even fractured as it was throughout history, including the belief in gods, etc. it has had the core elements of religion for a very long time.
The only "religion" that I can think of that isn't really a religion, that exists in the semi-present day, is Confucianism... and I still consider that a semi-institutionalized belief system, hence a religion, but it's not clear. It wouldn't be much different than calling the belief in democracy a religion.
