GR believed that people and society were more-or-less perfectable. I've never met or spoken to a writer on any of the shows who really bought into his Utopian "vision" of Trek's future.
I've never met Rodenberry, but I don't recall reading he ever used the word 'utopia' for Trek's future. The term seems to have been injected and used by others... but I don't think Rodenberry himself used the term.
Rodenberry was said that he was purposefully vague of what humanity was like in the 23rd century because his political views at the time were unpopular.
The writers who 'never bought' into Gene's vision of Trek's future also never met Jacque Fresco nor did they have a good understanding of human behavior or how it is shaped/influenced - they largely pushed forth some well established myths that were passed on in society but nothing that was grounded in proper science (at least not when it came to that).
Some writers did correctly use the notion that behavior is influenced by environment, but unfortunately, those episodes were not as common as I would have liked.
Why the fuck would I laugh at your expense?

Of course I am genuinely curious. I often times and reading Dr. Dan Siegel's research on interpersonal neurobiology and parenting styles. I was curious as to your synthesize of the data. That's how research works.
I asked for the simple reason because one cannot tell whether a person is being sarcastic or not when writing online... and I try to not make assumptions about people's behavior online (plus, people behaved sarcastically online without actually making an indication they are being sarcastic, so asking me about a book seemed a bit out of the blue to me, and unusual).
Yes, but having your thoughts and interpretations based on the science and data would be welcome. The statements made are made as though they are completely forgone conclusions without appreciating that not all of the readership has taken in this material. A book would provide sources and further reading rather than assuming a base knowledge.
I do not forget that a lot of people have not learned these things (that's why I responded to those posts), and the way some of them keep reiterating the premise that bad behavior is 'ingrained' into our biology needs to be addressed.
They keep repeating the same notion over and over (as you may have noticed from people in these forums too) which also gives rise to other problematic perceptions and behaviors that can arise.
Perhaps that is the case and we only see the exceptional people.
Perhaps, but I think it would be nice to stop with the idea that 'exceptional people' can only arise from having endured hardship.
It also sends a wrong message that if you keep at it and work hard, good things will eventually happen (its a common delusion in the existing system)
The fact of the matter is that reality doesn't work like that (and Trek and UFP are supposed to be better than that) and in the present system, if you are born in poverty, or fall in it, chances are you won't be able to escape it because the system we have doesn't work like that.
Wouldn't you prefer to have a society actively create conditions where becoming exceptional is not only possible, but encouraged and the norm?
Imagine what it would be like if kids come up with some interesting ideas and adults don't tell them 'don't be naive', but instead, 'what an interesting idea... lets see if we can test it out to see if it works or not?'.
