Good video. I haven't seen that one in a while.
It points out that it is not closed minded to hold onto a previous belief in the lack of counter evidence. This is the strongest defense of Religion/Strong Atheistism I have ever heard and a reasonably harsh criticism of attempts to change people's previous beliefs without relevant evidence.
I don't know if we were watching the same video but the one up there is pretty far from the "strongest defense of Religion". It even says there in the beginning: "Not only does believing in certain non-scientific concepts NOT automatically make you open-minded, it can often lead you to be the complete opposite.". The person who made that video is a known atheist. I wouldn't call his videos 'Anti-Religion', but they are definitely not defending religious beliefs or way of thinking, and I cannot see how you would interpret it like that.
What the video does is basically divide people into 3 groups:
1. People who are open-minded but have an 'evidence filter' to sort out true claims from false ones. (scientific method)
2. People who are open-minded, but lack the evidence filter. These people basically believe any supernatural story you tell them without having to present a single piece of evidence. They are what could be called 'gullible' and their understanding of reality is pretty random. If you go to any new age fair or other gathering, you will find tons of people with this way of thinking.
3. People who first accept false ideas uncritically, then close their mind from anything that contradicts those ideas, even when the evidence in overwhelming. A good example of this group would be religious people who follow the Bible and do not believe in evolution. They commonly say: "if evolution happened, where is the proof?". The thing is that there are a
million pieces of evidence for evolution but they are refusing to study that evidence because it contradicts their current world view. They are not really interested in finding the truth, they only want evidence that backs up their current views. That's the definition of closed-mindedness, and a lot of religious people belong to this category.
