I think most nudists are pretty libertarian in their views. Unless a guy like Tom starts aggressively shoving his hand up teenagers like he's Jim Henson in meth psychosis they probably won't do anything about it.
Although that said Tom enjoys forcing himself on other people regardless; he just fixates on kids and animals because they're easier targets. He'll happily worm his way into a nudist event that only features adults, since the concept seems wholesome and innocent, and thus he finds the idea of pushing boundaries and profaning it to be sexually thrilling.
