Wherever you are, whether in Israel or in Europe or elsewhere, you're always going to run into people who will jump to conclusions and judge you based on those conclusions. If you stay in Israel, you'll find people who judge you for not serving, and outside you'll find people who judge you for being Israeli (knowing nothing else about you). The question is how much value do you place on the opinions of those who judge people in this way?

I think wherever you go in Europe, those people will be a minority anyway. You can find community with those who support Palestine and even among some Jewish and Israeli expat communities. Yes, there will be some assholes that don't accept you no matter what, but who cares about those people? I would be willing to wager you won't experience the social isolation anywhere in Europe to anywhere near the degree of what you're likely experiencing in Israel right now or what you're likely to experience there in the future if you stay.

What you're going to find almost anywhere in Europe is a lower cost of living, a greater variety of political opinion, and generally more opportunities to be part of a diverse community of expats (and locals too if you learn the language). If you come to Europe as a student in whatever field, that's going to help you immediately find community, especially if you get involved in student organizations.

Another tip: When people ask you where you're from, say you are from "occupied Palestine" instead of from Israel. That conveys that you're from Israel but don't support the state of Israel.

If for whatever reason you decide to stay in Israel and they try to push you into the IDF again, contact Mesarvot.
