It is a similar issue in the US, in the rural red state patriarchal leaning areas. It is the androgynous young boys that are most often picked on as "the weak fish in the Aquarium".
The young man fit that "stereotype" of "potential victimization". It is also not an issue specific to the label of Autism in the US; however, the social communication difficulties make it easier for one to be taken advantage of by others. regardless if they are on the spectrum or are on a broader autism phenotype.
This is part of primate nature that is "watered down", overall, by civilization, starting with Agrarian way of life when the "Cooperator" became the prize over the "Protector". The result is the domestication of humans, similar to what one can sees with dogs and cats.
Not everyone is as domesticated as others are, still, in our day and age.
One "natural" result is boys playing with bombs instead of spears, per collective intelligence and more advanced tools to assert dominance. Culture and genetics both play a role in what leads to these type of events.
The "Warrior" gene still prevalent in the gene pool, can result in impulsive and reckless behavior when there are no tribal wars to fight. It is difficult to understand if one does not possess that "Warrior Gene".
The domestication of humans is moving faster ahead in Asian countries than the US. One can see that in countries like South Korea, where men are as interested in cosmetics as women are. Additionally, in countries like Japan, young people are losing interest in physical relationships with the opposite sex.
Where there is no competition for mates, there will be less bullying as a natural consequence of nature among males, but not necessarily the case with females, at least in the studies that have been done with some of our animal friends that have common ancestors with humans.
Location, Location, Location is important for the sale of the house and to avoid bullying.
It is easier than changing genetics and culture.
I understand that homogenous cultures such as the ones in Scandinavian Countries are some of the best areas for acceptance, but one will also usually find a leaning of reduction of Sexual dimorphism as well, along with the sharing of resources.
Interestingly, a key indicator is if it is a "gay" friendly area it is likely a safer place for almost every minority as that is a sign that it is not a heavy Patriarchal leaning culture oriented toward the "Protector" and "Competitor" rather than the "Cooperator".
