I think this is something that all liberals and conservatives can agree on. I mean, I'm all for gay marriage, but NAMBLA makes me want to vomit. There should be a law against them. I don't know on what grounds, but I'd like to see one enacted.
I guess as long as they aren't actively having man-boy love, and are only lobbying/advocating for changes in the law, there's probably not much that can be done.
