Of course. If something does not exist then it cannot be prove to not exist. For example, I challenge you to prove to me that you do not beat your wife.
No, I merely provided you with an example of what sort of argument you are making. If nothing has been done in violation of something it is rather difficult to show that is the case so, the onlus is on you to prove your case.as a positive can be proven whereas a negative cannot.
Au contraire, you have obviously never heard of the Stockholm Syndrome or the fact that denial by the victim is is common in domestic violence so it would not prove a thing.
It would provide a reply but would be proof of nothing and that my dear Snakestrecther is what this is about, the fact that a negative cannot be proved.
