No, IMO, "The line that no one put a gun to my head is O.K.," is not OK.
That could be said about anything that goes wrong. It's a way to make the victim look guilty, IMO. In this case, as someone else said, criminal activity cannot be glossed over by saying the victims should have known and nobody forced them to buy the stock.
It's like a rape occuring in a not-so-nice neighborhood and people saying to the victim, "Nobody forced you to go thru that neighborhood" or, "You should have known it was a bad neighborhood", etc.
It somehow offsets the guilt and criminal behavior of the rapist doesn't it?
Was that the intent of that post? I don't know...
Sure we need to be careful and take responsibility for our behaviors but we should never, never make a victim to appear responsible for being... a victim. LOL
