I am also Jewish, but people don't know unless I tell them 99% of the time. The only time I feel "different" is when from time to time people say incredibly anti Semitic things to me not realizing what my background is. It's usually near strangers and really jarring. This also happens with my sexuality (gay), so I've just sort of accepted it. I do code switch, I don't use any "jewish" words in random situations and I shift my natural speaking pitch down to sound "straight". It's been my reality for so long that it just automatically happens now. I think we are all different, but certain differences have a lot more stigma attached to them and it shapes the way you view and interact with the world. I also do not feel like I'm with my "people" in interest groups.
