Downfall of the Buddhist religion?

I feel that Buddhism is not what it used to be (the original teachings of Lord Buddha). It has got corrupted and what is left mostly relates terminology and worldly-matter and excuses. For-example: recently I came across a question in which someone said Buddhism teaches it is okay to eat meat, drink wine, etc. with various excuses such as it's okay as long as the animal isn't killed particularly for you and so on. I think, like Christianity and Hinduism, the teachings of Buddha are mis-interpreted for one's own benefits and the discipline with which Buddhism started out has long faded. Neither remains the atheism which Buddha preached, for example see: [this](https://buddhism.stackexchange.com/questions/13872/did-buddha-walk-on-water-was-jesus-trained-as-a-buddhist) . People have forgotten the abstract concepts and the Buddhist way of life and instead focus on miracles, folklores and powers that Buddhists monks possess. The question:
Do you think so too? If so, provide references of Buddha's teachings being mis-interpreted. If not, tell me then what was it that Buddha forbade, and if it was nothing, then why is Buddhism a religion? Shouldn't it be just living your life the usual way?
