I'm an amateur on the subject.
The man that did that video is far more knowledgeable on the subject than me.
Go to that video again and click on his pen-name and them research his latest video uploads.
I'm sure you'll find what you're looking for.
But I'd take the religious uploads with a grain of salty.
