How open you want to be with it is your choice - I can’t dictate that. When I meet new people, I’m not like “Hey, I’m Jewish,” but when I do tell them about it I’m fairly open. Other than that, I’m generally outspoken on the internet or if I see complete BS in public. My connection to Judaism isn’t the only thing I want people to see in me, y’know? You do you, though. Yeah, that’s typically true. Thankfully, I don’t live in an antis emetic area at the moment.
Honeslty i agree with the first comment. Used to be quite open… now in public (i live in London) i take off my magen david, its a scary time to be jewish.
