If there is sexual activity involving a minor, yes, the parents should be able to pursue criminal and civil cases. Solicitation without any actions doesn't seem that important.
Well, I'm pretty sure every state in the US disagrees with you and I'm not going to be continuing this conversation any further given that you think it's fine for adults to solicit sex from minors so long as "actions" don't happen (again, whatever the heck that actually means). I need to shower this thread off of me.
