I didn't read the entire post.
As far as I'm aware, it's not entirely sure whether homosexuality and pedophilia are similar. That's because it's unknown what exactly causes either of them. For example, there seems to be a correlation between being abused as a child and exhibiting pedophilia later on in life, whereas there exists no similar correlation for homosexuality. For example, children that are raised by a homosexual couple don't seem to have a higher chance of turning out homosexual themselves. (However, it's also likely that the former example is caused by some other disorder, such as PTSD or BPD.)
One explanation I once heard is that the brain prematurely ceases or "skips" an important development that makes the individual be attracted to mature people.
You'd say, from some point of view, that since homosexuality and pedophilia both deal with sexual preference, they're likely to stem from a similar source, but I don't think that's the case. But it probably will take a while before we figure that out because of how difficult it is to accurately analyze the brain's function.
I think ASE should reply here since he's probably the only one with an educated answer.
I think that the one thing everyone can agree upon is that it is a despicable practice that deserves absolutely no form of encouragement from anyone. It is something that is not socially acceptable under any circumstances and is punishable by law for very good reason.
By the way, I'm sure everyone knows this, but there's a difference between being a pedophile and acting upon the urge. Whenever this topic comes up, people are all too eager to speak their mind about how we should persecute pedophiles, but we kind of know those things by now. It's much more interesting to just set aside that discussion for a while and discuss the actual
disorder.
