Women from this demographic aren't used to seeing fathers with their children and see men with children as potential abducters in a way that those from non-dysfunctional groups would never do
You have made two MASSIVE and unsubstantiated claims there:
'aren't used to seeing men with children'.
I live in a country where the vast majority of people are over 10 years old, does that mean I am not used to seeing anybody under 10? no.
'and see men with children as potential abducters in a way that those from non-dysfunctional groups would never do'
You have essentially claimed NO happily married could would ever see a man as a potential abductor. The phrase 'would never do' is far too dismissive.
Different people will interpret different situations differently. A man with a child needn't be seen as a potential abductor, often it's quite the opposite - depending on the context and interaction with the child.
However, in SOME contexts (a child reluctant to go along with the male, or seemingly protesting) might give rise to some people interpreting it as an adult struggling with an errant child, whilst others might pause for thought and wonder if there is something more sinister taking place.
Your assertion that 'chavs' are more likely to interpret this situation in a way that others never could is absurd. There are countless other factors that will influence the interpretation, to a point where with enough supporting evidence, almost all people would interpret an action as abduction, even if it's not.
For instance, if a father were to put their hand over a child's mouth and drag them off into a van, and a mother screamed - then that would almost universally be interpreted as an abduction, even if later it turned out to not be the case (the man accidentally put his hand over the child's mouth, they were in an extreme hurry to leave, and the mother screamed because she thought the van was going to collide with other traffic)
If however an abductor pulled up in a Rolls Royce, called out to a child and the child ran to them with open arms and shouted 'Daddy!!!' - HE could be an abductor (intending to take the child away from his estranged wife), and yet few would consider it an abduction based on the scene before them.
Do you still maintain 'chavs' are more likely to assume abduction?
Do you not concede there are many other factors that will influence the interpretation?
