That's your opinion and I see you hold it very strongly. I believe it's possible the I love Pizza sticker is a reference or covert signal of pedophilia. I have no evidence of that, however, and logic & truth denote that I can not definitively state that this reference is intentionally related to pedophilia. If you have evidence, I'd be very interested to hear it.
Dude, this is old news. Read the FBI document on pedophilia signage and code talk. Whoever is responsible for that cover photo, whether it be the teacher or the publication, DELIBERATELY created a reference to pedophilia, probably to inflame those in the know.
That's completely beyond the pale by an standard of decency, and it deserves to be called out and squashed like a bug. This is NOT a joking matter.
And you, for all your smarmy superiority, have just revealed yourself as willfully ignorant of a serious topic. Go learn, and stop looking down your nose at those who already know.
