First of all, I'm still waiting to hear where I called you a liar. It's a serious accusation which you have repeated several times, and which I believe to be wrong, so I believe some actual evidence is in order.
It was the equivalent of saying if I have any examples of water being wet please tell you elsewhere - and you know it - deliberate belittling insult pretending reality is not real just to push your agenda.
No, it isn't. Here's the evidence that water is wet. It is easy to produce, because it is both true and actually self evident, unlike your statements.
Your point, however, is a contested one. As such, you shouldn't act hurt or surprised that someone asks you to substantiate it. In essence, you are accusing me of lying, of claiming something different than what I believe in. I reject that accusation. I truly believe that criticism against Israel is not self evident and needs substantiation.
When you are stating that this is self evident and requires no proof, what you are doing is not to show it is true. What you are doing is to show that you are holding it as prejudice. An opinion based on belief rather than facts.
As for the BBC accusation, please do post a link if you want to discuss it. Your abstract makes no sense. You are presenting accusation of misrepresentation as proof that these accusations are wrong. Again, this might align with your prejudice, but is not proof of anything. The BBC could be unfairly misrepresenting the truth, in which case Israel would have a valid cause to complain.
