Man, it sure is a good thing this exact rhetoric wasn't completely recycled 65 years later by the very people who were targeted by that first moral panic.
We definitely don't have widespread panic from social conservatives about how teens are being groomed into being queer by a vast conspiracy that has resulted in action from Congress. Nope. Never happened again.
(watch Matt Baume's video "Is Rebel Without a Cause a Gay Movie?" and then the rest of his videos because they're fantastic)
I can also say unequivocally that if I'd seen Rebel Without A Cause as a teenager, my immediate first response would have been 'what if there were vampires in it. they should have put vampires in it' so props to Joel Schumacher on that one.
