Being a paedo is clearly always going to be different to being gay, as paedos don't have sex with each other, they rape kids. Homosexuality is between consenting adults, but pedophilia never will be.
But at some point someone is going to have to come up with some solution to them, as it seems very optimistic to just expect them not to act on their urges through fear of prison sentences and the obvious "kill them all" solution isn't exactly practical. Ideally you'd want some system in place for people who are attracted to kids to be able to admit it and get some kind of help, rather than only finding out about them when they do something awful. All that being said, I can't see how creepy kid sex dolls is the solution.
