Well:
(1) there is no "the general public's gut" -- the general public is millions of separate guts that don't agree with each other;
(2) our political system defines explicit boundaries for the reach of regulatory power, especially where communication, expression, and social interaction are concerned, regardless of anyone's gut feeling on these issues;
(3) science can't be the arbiter here at all, since science only answers "is" questions, but this is an "ought" question; which leads us to
(4) as you alluded to in your final remark, this is a purely cultural issue which families/parents must address according to their own normative values, independently of each other, and there is no legitimate political or legal question here.
