Addressing the question of "Why do we like this?" and Mental Health

I've been wanting to write more about the psychology behind adult babies. This is a subject that is way to complicated for youtube comments. It would probably be a series of blog posts. I've been meaning to dig out my old psychology textbooks, but life is just too busy.

I just made 3 posts in reply to the last post of someone from a week ago. He questions our mental health but does not seem hostile and seems to understand that he has no facts to back up how he feels. I think he genuinely wants to understand what is going on in our heads. He just feels that there must be something wrong.

I thought the discussion got more interesting when he question if an AB would still be an AB after twenty years. At this point I am only going to post my comments and let you read between the lines to figure out what they wrote.

There are a lot of adult babies out there and different ABs give many different answers to the question why they are an AB. Assuming that an individual does attribute their fetish to a traumatic event there is no way to tell for sure if things had been different that they would have turned out AB anyway. And nearly all ABs who have psychological issues remain adult babies after they have resolved those issues.

 There are exceptions, but for the most part yes. I've been doing this for almost 20 years. I have AB friends who are in their 60s who have been doing this longer than I have, and I once saw an AB at a convention that had to be in his 80s. This is just something that some people really enjoy doing. This isn't any more likely to change than someone who enjoys certain genres of music or literature. Would you expect any different from people with other kinks such as people who enjoy spanking?

part 1 - This is a difficult issue to understand. There is not enough room in youtube comments to explain it adequately. I appreciate that you have been civil in your replies to my comments. I also appreciate the fact that many people get an uncomfortable feeling when they first learn about this fetish. You are having an emotional reaction and that is not something that you can control. This is why I try to stick to the facts.

part 2 - Your instincts are telling you that there is something wrong, but instincts can be wrong. Conc0rdance has a good video on this called "Common Sense Is Worthless in Science"
Assessing someone's mental health is a medical claim. It needs to be looked at scientifically with real world evidence, not simply declaring that someone is crazy after watching a "Reality TV" show. Unless you can provide evidence, you cannot rightly claim that there is a problem with someone's sanity.

part 3 - Curiosity is something to be admired. Asking questions is a good thing. I think that you actually are interested in real answers.
Why do people like this? The answer is complicated and in fact there are different answers for different people. Another question is why do people like anything?
It is more complicated than this but there are areas of the brain that when they light up you are happy. Any number of things can stimulate these areas and this varies from person to person.

I re-wrote the middle of part 2. Here is what I first wrote and then changed to medical claim and science:

If you are going to question a person's mental health, you have to have real world facts to support your claim that there is something wrong such as they are "a threat to themselves or others."

I liked this but felt that what I replaced it with was more in line with the idea of common sense vs science.
