I suppose it could. Although, I think the left tries to limit it(so far, anyway) to “consenting adults”. Remember a few months ago when Hollywood director Nick Cassavates supported incestuous relationships using the same argument that the pro-”same sex marriage” crowd uses? He was just being consistent with the ultimate conclusions of where the liberal arguments ultimately lead to.
“consenting adults”... in Hollyweird the child stars have usually slept their way to the top
