Either you are being completely disingenuous or you haven't really understood the article. It doesn't say that hugs aren't allowed, it's simply a case of letting children refuse physical contact if they choose.
So, if you asked, pressured or guilted a child into hugging you, then yes - it is aimed at you and you need to re-think your behaviour.
If you enjoyed mutual hugs with the children who were happy to give and receive physical affection from you, then no - it's not about you and there's no reason to think it is.
