The reason people record video is that they've learned that if they don't often people more powerful than them claim that things didn't happen, it was just in their head, they're hysterical etc. This is especially important IMO if you're a working class woman - it's easy to be silenced if you don't have the money or time to go to court and people know that.
Do we really need to state that having no evidence often goes badly for poorer women - grooming gang victims, anyone?
That doesn't excuse sharing it without other women-in-the-video's consent but it is a powerful reason to take a video in the first place, especially when others are also filming. Which I can sympathise with - once someone is filming you've lost the 'not being filmed' position irrevocably. It's likely that as soon as one person whips out a phone then there will be at least 5 or 6 others doing so too.
I've heard at least 5 versions of what happened with the Jewish woman at the disco. What's interesting is the way people relay their opinion. Some are aggressive, others are more obviously neutral. I'm more likely to believe the neutral ones and those who don't declare with absolute moral certainty exactly what happened and what everyone's motivation was (including mine when simply asking questions, implying I'm not in good faith) and absolutely no nuance or room for the slightest uncertainty.
E.g. in a positive sense Shinyred describes what she saw but is clear that it's her interpretation that the Jewish woman getting the yellow ribbon out was in response to the flag wearing / pro-Palestine chanters. And that this interpretation may be wrong. That makes it more likely I'll believe her.
Because other people are declaring with absolute certainty things that are later proven as untrue and that tends to make me slightly wary of what they say and what their motivations are - particularly if they're generally quite rude to anyone who has a different opinion and seems to think everyone else should just accept their version no questions asked.
In terms of what happened I don't really care at this point, time to move on, except for hoping the Jewish women who were there are ok and generally feeling more resolved to speak up about antisemitism and pay attention to it as someone not Jewish myself. I hadn't seen a lot of the more extreme and virulent antisemitism that Jews in this country are exposed to until this week, so it's been a wake up call.
