Why?

First I didn't call "us" only you a liar.

Secondly you start off with "The recurring claim ..." there is no such "recurring claim". I have provided the reasons for which it is now commonly acepted that the refugee problem arose.

Thirdly, you state that a call for evacuation by the Arabs themselves was not a contributory reason for the refugee problem when plainly it was and for which independent evidence exists. You thereby imply (and presumably why you posted in the first place was to suggest) that the main reason is the oft repeated canard that the Arabs were expelled by Israeli forces.

I await your next wriggle.
