Might be aimed at adults but children follow what their parents do including politics and activism. Do you really think children dragged along to anti-abortion protests, equal rights protests, etc, aren't absorbing their parents attitudes?
From a personal perspective, I'd say that's not always the case. I ended up with two very far right sons! That is not the type of home they were raised in. My sister and I were raised by liberal parents but my late sister became a sign carrying anti abortionist and avowed hard core conservative.
