There is a much bigger and long-running situation. The problems didn't start on October 7th. This current crisis has been going on for 3 generations running. Palestinians have been under Israeli blockades longer than some of the people using the Internet have been alive. The small minority Christian population of the region has been living between the hammer of Israel and the hammer of the Islamist militants. Muslims who convert to Christianity face persecution and many have been forced to go into hiding. The big churches there aren't the only Christians. Smaller groups of Christians and the occasional converts from Islam to Christianity have sometimes had to 'go underground'.

Aside from that, the Christian community in Gaza dates back to the 4th century--even before Islam entered the region. Then Islam entered and eventually the Ottoman Empire, and the British Empire. There is along history of the Christians of Gaza dealing with all of that, sometimes resisting, sometimes just resigning themselves to the situation.
