Are there Christians in Israel? Are they discriminated?

Yes, most people in Israel are Jews. Around 74% of the population in Israel identified as Jewish. The remaining population is comprised of various ethnic and religious groups, including Arabs (who are predominantly Muslim, but also include Christians and Druze) and other smaller minority groups. Please note that these statistics may have changed slightly since then, but the overall trend of a Jewish majority in Israel is still accurate.
Yes, there are Christians in Israel. Christians make up a small minority of the population, accounting for around 2% of the total population as of my knowledge cutoff in September 2021. The Christian community in Israel includes various denominations, such as Greek Orthodox, Roman Catholic, Armenian Orthodox, and Protestant.
In general, Israel is a democratic country with laws that protect the rights and freedoms of religious and ethnic minorities, including Christians. However, individual experiences of discrimination may vary, and there have been some reports of tensions between different religious and ethnic groups in the region.
It is important to note that the situation in Israel and the Palestinian territories is complex, and the experiences of minority groups can be significantly different depending on the specific location and context. While the Israeli government officially promotes religious freedom and tolerance, individual cases of discrimination may still occur.
