If I was to go go by my personal relationships I would say yes. However I tend to draw unhealthy minds to me like honey draws ants.
There are many who have sociopathic tendencies but are not clinical sociopaths.
LGTB do have more than their fair share of mentally and emotionally 'unsettled' people, due to how we are treated for being gay.
It would be unfair to say that most people who
appear to be sociopaths ARE sociopaths. Such as the apparent of lack of empathy, a lot people flat refuse to show concern, or open themselves up to personal hurt because of harm they have received in past. As such, they appear to have sympathy, empathy and other stuff. Its not that they don't feel these things, its that they are hard at work protecting themselves thus hide those emotions.
To be fair, people in their 20's are not that stable mentally and emotionally speaking. The brain doesn't fully develop until age 25
http://www.bbc.com/news/magazine-24173194. as such people are still undergoing mental changes which will affect their personality and their behaviors.
"
Neuroscience has shown that a young person's cognitive development continues into this later stage and that their emotional maturity, self-image and judgement will be affected until the prefrontal cortex of the brain has fully developed. Alongside brain development, hormonal activity is also continuing well into the early twenties says Antrobus." (from that link above).
So at your age chances are high you will be dating a lot of immature guys because they have yet to be fully and completely developed, matured biologically and chemically.
Then there is the fact that you kids are still dealing with replacing childhood notions of what life is like on planet earth with real hard experience as an adult in the real world. Fantasies are faced with harsh realities. if your parents were half decent at their job while you were a child you were shielded from the many issues of life on earth, thus have a biased, slanted view of what to expect.
This sort of thing has impact on behaviors.
And yes a lot of 'kids' behavior like sociopaths or psychopaths but are NOT clinically either. They are 'just kids' who have yet to figure out how to function in the modern world and deal with the realities of such things like relationships.
