CSE, since you have already revealed that you know next to nothing about Buddhism, and have no interest in studying it yourself, why do you feel that you have any capacity to decide that there is anything 'wrong' with it? And if you have no interest in learning about it, why do you keep spending your time on this forum? Just to try to convince people to stop being Buddhists? Well, I have news for you, most of us are lost causes. Why? Because many people here, such as myself, have had many many direct experiences with human beings that are realized-- that are not ordinary-- that display vast wisdom and compassion that is contagious and that transmits itself directly to our own minds (or reflects our own wisdom back to us) in the best of circumstances, -when we are open enough to receive it. These direct experiences of vastness and compassion function far beyond the intellect, beyond simple 'knowledge' in the way you intend it. So despite what you seem to believe, this is not a lineage of book-learning, or simple knowledge. It is actually a holistic lineage that values study, but also direct transmission, meditation, relationship with spiritual friends, etc. So the degree that we have already been transformed by these relationships-- to that degree we are beyond hope of being convinced even in the slightest by an anonymous internet persona that can hardly write decent english sentences. So I would suggest you reevaluate your purpose for being here!
