no, that an event or object is socially constructed does not merely mean that we can't get at the 'an sich'-ness of the thing, it means that there are structured (and structuring) ways in which we render objects and events. whether someone is rendered freedom fighter or lewdachris isn't a function of the non-determinate character of the thing itself, but an effect of structured dispositions to 'think, percieve and act' in those who produce meaning.
the suggestion that there should be objects or events outside any meaning prodcution is unbridled idealism --
