The Left uses humor to desensitize people to morality.
Exactly right. Hollywood will try to "normalize" pedophilia using the same playbook that they used for homosexuality. It won't happen overnight, they'll phase it in gradually. You'll start seeing TV shows where a passing, non-judgmental reference is made about an unseen character being a pedophile. Later, they will start showing up as minor characters in TV and movies. After that, they'll have recurring roles on sitcoms as the "goofy but harmless" neighbor or coworker. Eventually, these programs will include a dramatic episode about the recurring pedophile character being the victim of a hate crime perpetrated by a "narrow minded bigot" who disapproves of his lifestyle. The wheels are already in motion with "comedy" skits like the one described in this post.
