Also, kissing kids doesn't make someone a pedophile, it's a cultural/social norm for some people, creepy as it might seem. I'm not advocating it but it's still not pedophilia. Also, it's been shown that pedophiles generally don't maintain relationships with adults because there's no attraction, the Right bandy it about as an insult so often that they are at risk of drowning out real concerns.
