It doesn't seem that disruptive to me, but trying to portray it as a Marxist anti-family statement is still a stretch. It appears to advocate "disruption" of the nuclear family model through greater community involvement rather than "disruption" through dismantling it. It's still not an anti nuclear-family statement per se, it's just against having the nuclear family unit being the only relevant influence in societal upbringing.

Which in a rural white community would literally be a Sunday church sermon.
