This specific story aside, the point is that for those in their teens, it's very possible that expressing those views is being done to "rebel" rather than as a true belief or as an opinion held with the full appreciation of its implications. i.e. the act of holding such a rejected view is the point.

Which isn't to say such views should be tolerated, merely that the approach taken for interacting with such individuals really should account for that.
