The poster you're responding to is dispensing advice on how to handle and escape from predators. Accusing them of victim shaming is wrong, and you're just siding supporting the predators by doing so. It's good advice.
"to is dispensing advice on how to handle and escape from predator"
No - his advice of 'applying assertion' is definitely wrong in this context, where the advice should be 1) leave or 2) bend like a reed in the wind and avoid avoid avoid. Reacting to antagonizing - even if the victim knew how to do it, would likely yield more blowback - and more likely, the victim would have no idea how to assert themselves.
The situation is not like 'physical assault' where you have nothing to lose from fighting back.
Inability to pushback is not a function of decision or character, it's a function of the crazy power dynamic.
If the victim had US citizenship, it would have been much easier to hold ground, for example.
Sounds like the kind of person who wouldn't last long in jail. "Hey you really shouldn't let him steal your peach cobbler. You need to push back." and gets his ass shived nine times.
That's victim blaming to the extent there is nothing someone can do to assert themselves other than basically leaving.
