Buddhism shouldn't be a religion because you shouldn't be praying to the Buddha and expecting him to answer, as many people do in temples across Asia.

Why not?

The Buddha achieved enlightenment. He's done. He's become one with the cosmos and is beyond caring. Praying to him does nothing but make the person praying feel better, and simply reinforces the illusion that is reality. The thing with Buddhism (which when correctly followed is better considered a philosophy rather than a religion) is that he could only teach the path. It's up to each and every individual to find their own way.
