Yesterday, I happened to use a Gisha graph to illustrate the difference between how Israel has been improving freedom of movement to and from Gaza compared to Egypt.
Versions of this graph had been featured on Gisha's homepage for over two years.
The day that I used their own graph to show how Israel is helping Palestinian freedom of movement - something Gisha is loathe to admit - they changed their homepage to eliminate that chart:
As soon as I used their own chart to prove something contradicting their entire purpose - which is to demonize Israel - they removed it from their main page.
I'm sure it is just a coincidence.
