Personally, I don't see any reason why someone should be concerned with what someone else puts up on the internet in a blog like this.
---Like it or hate it, it provides some good points for discussion.
Decide for yourself if your training meets your needs. Lots of people seem to have a Life Mission to try and discredit anything that anyone else does if it does not conform to their own narrowly defined ideals.
---Good advice.
I ignore articles like this one. I have ignored this article too. It's not worth the time it takes to read it.
---How do you know? You didn't read it! Even if you disagreed with what Rackemann said, it would make you think about WHY you disagreed. You might even end up realizing that at some level there is some truth to what he says, even if he does take his points a bit too far at times. That's the reason for posting topics for discussion. If everyone agreed, then there would be nothing to discuss. But if you won't even consider the topic, how can you discuss it?
