No idea, maybe? The call to protest outside the cinema that I've seen doesn't mention it, it mentions protesting against the screening of the "Zionist propaganda film". So clearly the film itself is considered an issue by some, not whether or not it's part of a film festival.
The film is a documentary about the massacre. A bit fucking disrespectful to be protesting that, no? I thought we all agreed what Hamas and their friends did was beyond evil, and 100% unacceptable.
If people protest the screening of the documentary I think it's time to think about what the morals and beliefs of these protesters actually are. To think about whether or not they're showing any kind of humanity, or if they're just being insanely disrespectful to these victims of terrorism and treating them as though their stories aren't worthy of being told. Treating them as unimportant.
Protesting outside this particular screening is just going to isolate and ostracise the Jewish community further. If people are ok with that, I'd ask you to think about why you're ok with it. Is it what a previous comment said, since deleted for being anti-Semitic, and that people think Jews can't be trusted to tell the truth about antisemitism and will exaggerate it? If so, do you also think women exaggerate if they say they don't feel comfortable walking alone in town at night? Why aren't Jewish concerns taken seriously? Why are they so regularly dismissed?
Why can't the organisers just agree to take responsibility, and actively uninvite those who attend for anti-Semitic or pro-Hamas reasons? Make it clear they're not invited, not welcome to attend. Name and shame them! Deal with the issue, stop just ignoring it.
Ugh.
