Yeah meeting new people isn’t easy once you’re out of school. If you are outgoing there are definitely avenues though. There are meetup groups for everything. You might not have hobbies, but you still do things. You bike? Go to the local riding meetup. You like boardgames? Sign up for your local open play at a boardgame store. You cook? Take a cooking class at a kitchen store or co-op. Anything you do, there is probably already a local group meeting up to do it.
The problem is that it’s easy for the interested parties to equate it to antisemitism when intermixed with legitimate protest of Israel’s horrendous actions are actual antisemites coopting the conversation for their own purposes. Antisemitism is at it’s highest point in my entire lifetime. Things to note: Muslim Israelis (about 20% of their population) support Israel’s wartime actions at about the same rate as Jewish Israelis. Also, the language used in opposition to, or in support of, Israel in this conflict is different than in comparable one sided wars.
To be clear I want to reiterate that i think what Israel is doing is undeniably awful, but I think antisemitism, and anti Muslim sentiments, color how people interpret and talk about what is happening irrespective of government officials agendas. It’s absolutely part of the conversation whether we like it or not, and we have to navigate that as part of the larger conversation. This isn’t to say I don’t agree with you, it is bullshit to just paint everything as antisemitism.
