@Mynameisnew - yes, there are far fewer of us than most people think! I find it interesting to ask people how many Jews they think there are in the UK most people assumed 'a couple of million maybe?' but no, there's only about 300k of us. We do punch above our weight culturally and are very concentrated in London (about 200k out of the total). And this is a problem as a lot of people don't know any Jews, which is probably at the heart of a lot of antisemitism. I can imagine people thinking 'Well, these Jews obviously keep themselves to themselves, they must think they're better than us' without realising it's just there aren't many of us about.
I've never experienced antisemitism on the street, but then I don't 'look' Jewish, I have an Anglicised name. I do sometimes worry someone might yell something at us one day when they see us obviously walking to synagogue (when my husband would usually have his kippah on his head) but it's never happened.
I have experienced it a bit online - for example, people who feel I owe them my view on Israel before they'll engage with me, for example. As it happens I abhor the treatment of the Palestinian people and feel they should have a state - but the point is I don't owe anyone that just because I'm Jewish.
I have the privilege of not having to be too worried about antisemitism myself, and I don't see any existential threat for Jews. But certainly more could be done to educate people to understand that... Jews are people! We don't all think or look the same way.
It would be good to teach that the origins of a prevelance of Jews in finance, for example, os not a sinister conspiracy but originates in the fact that Jews were historically not allowed to have many jobs except moneylending - and were then villified for being greedy and obsessed with money.
