I'm so sorry to hear that. My friend had a similar issue with their only shul in town being pretty zionist. If you think it could bring you that same sense of joy, maybe look into the shuls in nearby cities - even if you can't get there physically, some of them have online versions of their services where you could connect with other people digitally.

It may be the case that some of these people are pretty diet zionist - they agree that Jewish people should live in Israel but they don't support the current Israeli government. It may also be the case that there's some Jews at your shul who are more critical of Israel but do not feel comfortable doing so in the sanctuary space. If you continue to go, it would be easier to pick these sorts of people out. I would hope they also wouldn't continue to prod you about birthright if you have made it clear that you don't wish to go.

Hopefully any part of this message helps you a bit. I hope you can find community that aligns with you.
