I'm a Daoist. Teaching my children techniqes of meditation, which have positive influences on mental health (don't even @ me, I will flood you with peer-reviewed citations) is abuse? Teaching them the benefits of regular exercise is abuse? Teaching them to pay attention to what's going on with their bodies is abuse? Encouraging honest self-reflection is abuse?
It is very much a religion. It has gods and goddesses, scripture, ritual practices, priests and monasteries. I know in the West there is some confusion, but mostly because Asian societies do not tend to make that divide.
On the other hand, Doaism is not really dogmatic, so nobody really gives a shit if you believe in this god, that god, or none at all.
That's where the question comes into play. The set of beliefs without requirements for worship make it a philosophy rather than a religion. A religion that does not require beliefs but rather suggests practical implementations doesn't fit the same structure as the other major world religions.
Anyway if your beliefs require indoctrination of children to believe in myths and legends as a coercive means of control it's fucked.
If it does exactly as you say above: it's not a religion it's a philosophy, because it does not use myths and legends as coercive means of control.
I think the spiritual points of some regions are not as bad, but teaching the prejudice and idolatry of some of them I believe it's not good for children and should be seen as child abuse.
