I don't think this is an unreasonable view, but it does seem to me that the declining Christianity rates aren't super useful on their own for determining actions from a systems thinking perspective.
Maybe rates are declining because the religion is legitimately not appealing, in which case your action is right. An opponent would say that it's declining because it's culturally discouraged (since even religious pockets are exposed to the national zeitgeist), in which case ignoring it would be the exact opposite of what we'd want to do.
I have thoughts on why religion is declining, and I don't believe it's because it's culturally discouraged. Young people want community, but they do not want to be told what to do by a hierarchy and spiritual leaders simply because "they say so" and related historical texts. The power and control through belief systems and hierarchy inherent to religion are breaking down. Is it because of social media [think increased velocity of cultural Overton Window and societal norm transition]? Younger people are more empowered and can support themselves while avoiding these institutions? Brain structure changing as it relates to social needs, fear, and tribalism? Hard to say yet, but I am excited to understand over time as a scholar.
For comparison, Japan legislated that religious indoctrination and withholding education or healthcare from your children due to religious beliefs should be classified as child abuse.
