Its nothing like that. Listen every religion except Hinduism has a strong base.
Hinduism is a religion which literally worships anything it can find. It is such a faith which can bring in new gods and worship without hesitation. Before and during Lord Buddha, hindus used to follow something else. Afterwards new gods came and some old god's became unpopular What I am trying to say is that Hinduism went through a lot of reforms.
Buddhism is not like that. We cannot invent what lord Buddha said. It has got nothing to do with Buddhism being Abrahamic or Eastern faith. Hindus can do whatever they like but if you follow Buddhism then you will have to follow guidelines. And yes, Lord Buddha was very strict when it comes to rules. He was more than a philosopher.
We Buddhists will never let Hindus sabotize our faith. Hindus have been trying to assimilate us into Hinduism for thousands of years but failed.
