Look:

See that nice guy in the park? Do you know when he’s not walking his dog he’s torturing it? The woman at the bake sale has a picklejar full of self-aborted fetuses in her basement fridge? the mohel at the local temple has a wetsuit made out of his foreskin collection?

You don’t think these things are true? if you don’t suspect everyone of nefarious activity you are a fool. if you don’t look at the world with a jaundiced eye you cannot be prepared for how fucked up it is. And trust me, it’s a lot more fucked up than you can possibly believe.

That doesn’t give you any business being rude or inconsiderate, and it doesn’t give you reason to be mrs Kravitz, calling the police every time you see something that scares you going on across the street, but you need to be aware that there are a world of assholes out there. Don’t be surprised by the bullshit they do.
