My big takeaway from all these conversations is two key problems I have identified:
ANTI ZIONISM
To have an opinion on something, you really need to understand it. And I have come away from these threads feeling most people don't. Starting with the obvious, a fair few people who were declaring themselves "anti zionist" turned out to be simply "anti the current Israeli governments actions". Which is not even close to the same thing.
To have a fully informed opinion on this, I think you'd need a nuanced understanding of the full history. I think you'd need a nuanced understanding of the different ways of life in the Middle East and how minorities live and continue to. I think you'd also need an understanding of antisemitism and how anti zionism has become a vehicle for that to be expressed.
These threads have all been full of people posting false information, or information which is so heavily biased that it would be fairly useless. Having studied history for 20 years, you will always get conflicting accounts and there's a degree of hypothesis involved where things will be heated debates - but you don't usually get people saying things which are just completely not true.
So my conclusion generally is that the majority of people don't fully understand enough of the information to even be anti zionist in the first place, and a larger number probably haven't through through or understood what it means. So maybe it's a shame people feel so confident in throwing the term around. It's a shame Jews have to deal with that.
ANTISEMITISM
Similarly, these threads have confirmed what I already knew. The vast majority of people don't understand antisemitism, haven't bothered to read or understand the definition and will engage in it either without knowing or without caring. They will even be confident enough to tell Jews they have it wrong. It's a kind of collective arrogance that's quite mind blowing.
All of this is fairly reflective of my experiences on Twitter or IRL - so I suppose it might be a good reflection of the state of the country. We have a lot of people with very strong opinions on things they haven't taken the time to really understand.
