For you, they now are your tastes, but if those tastes were acquired by nurture, they don't have to be your children's tastes.
Given some tastes lead to less power and riches in our current societal environment. If they are nurtured, it is logical for parents to want to nurture them to more lucrative alternatives.
If they are innate though, it's a waste of time to try and change them. So I feel it is definitly somewhat relevant to know.
