When you're the only one who follows a set of traditions and rituals in an area, it does indeed feel quite strange. Holidays are lonely, even shopping for goods can feel alienating. And the casual antisemitism... its often small things, but you often hear odd comments or off color jokes, the kind of things people casually say because they are certain they aren't offending anyone in earshot. I'm not sure I'd ever move just to be closer to more Jews, but it is very comforting to know you have instant community in an area. I remember coming back to the East Coast USA from the Southwest and nearly breaking down seeing mass produced hamantaschen in a bakery (even if my homemade ones are way better).
My sympathies go out to this lonely man and I hope he finds a way to feel connected to others in that unique way tradition and community evokes. Though the article makes it sound like he's built a life he's happy with and that must be very rewarding in its own way.
You get a lot of information, but it isn't news relevant to your life. It's information meant to upset and disturbing you so that you pay attention to it, not because it's a threat to you, but because then the website can get paid for pushing advertisements for products you don't need under your eyeballs.
Give it a shot for a month or so. Stay off social media, only use direct contact communication with your friends and loved ones. Instead of news, talk to them about anything else. The world indeed will keep spinning, but you don't need to know to worry about every little turn. It'll be in the same place when you're done with your break and your observation of it won't change the trajectory.
