I wasn’t able to find the same Quote in a more reliable source, but I was able to find about 6 difference Websites quoting Abbu Sitta with this. The Quote also was(if I remember right) why he was denied(unlawfully) Entrance into Germany and France. plands.org/…/i-could-have-been-one-of-those-who-b…
I will try to find a more Serious source and link it then.
Edit: sadly i was only able to find a german Article regarding the palestina conference and why it had been stopped by the police: taz.de/…/
In the Article they say the following:
Grund für die Polizei, den Video-Vortrag von Abu Sitta abzubrechen, war offenbar ein Blog-Beitrag des 87-jährigen vom Januar. Darin hatte dieser geschrieben, wäre er jünger, hätte er einer derjenigen sein können, die am 7. Oktober die Blockade des Gazastreifens durchbrachen. Beim Überfall der islamistischen Hamas waren etwa 1.200 Menschen in Israel getötet worden. Als Redner war Sitta allerdings schon seit Monaten angekündigt, sein Vortrag also alles andere als überraschend. Dennoch griff die Polizei mit voller Härte durch, als sei akute Gefahr im Verzug.
Translation:
The reason for for the police to stop Abu Sitta’s video presentation was apparently a blog post a blog post by the 87-year-old in January. In it he had written had written that if he had been younger, he could have been one of those who who broke through the blockade of the Gaza Strip on October 7. During the attack attack by the Islamist Hamas killed around 1,200 people in Israel. were killed in Israel. However, Sitta had already been announced as a speaker for months, so his speech was anything but surprising. Nevertheless, the police cracked down as if there was imminent danger.
