I am often left confused by responses like this. I think it would be fair to suggest that some significant percentage of chidren suffer in schools or have harrowing experiences that they are going to carry with them through life until dealt with. If this is the case, why on earth should a conclusion about school _not_ be drawn? I don't believe you are meaning to suggests that the situation as it stands doesn't need change, but that is nonetheless implicit in your statements.
From my position, saying: "I'd be wary of drawing too many wide-ranging conclusions about school education as a whole from it." Comes close to invalidating the experience of another.
