They are indeed emotionally immature. I have seen behavior like this by small children in the stores throwing their childish temper tantrums. It is normal for children to sometimes act like this but not for grown men. These guys are still in their terrible twos. The more you look at their behavior closely, the more you can see that it is a deep seated issue from early childhood. This is arrested development written large.
One time I was in a store when a young child threw a temper tantrum. I had seen children do this before even my own children but this time I looked at the behavior with new eyes. I wondered what a child would be like if the parents didn’t deal with this immaturity properly? If parents fail to bring the small child from their immature overly emotional point of view to the adult point of view, the child would grow up to be a immature, dysfunctional person. This is what you see in homosexuals. Many of them know how to mind their manners in public even be successful and talented but there is something there that is just not right. And it obviously has a lot to do with sexual identity. There is something about not identifying with the right parent. Psychology has done much work on the causes of homosexuality and they were right. The same thing is true about transgenderism which is a branch of homosexuality.
Because far too many homosexuals define themselves -- at their base level -- not by their accomplishments or their acts of charity and the like, but by their sexual preference. Hence, all the "PRIDE - Proud to be a Homosexual" celebrations that are so very well-attended.
I think that if that is what they consider their base reason for their existence it creates all sorts of problems (such as easy acceptance of a "herd mentality") ... many of which may be unintended and perhaps even unrecognized by them, but the problems exist nonetheless.
(I assure you this is not an amateur attempt at psychoanalysis; rather, it's just a conclusion I've reached from my observations and interactions with many homosexuals whom I know ... a few of whom I adore (uhhhh ... in a Platonic way, of course! ... as they are fine people who at least take time to consider an alternate viewpoint ... but those folks are exceedingly rare.)
