Chrstian Arabs are more anti-Jewish and more anti-Israel than the moslems. It's also chrstian Arabs who make up the bulk of Communists in the Arab world. The chrstian village of Nazareth had a Communist mayor for years because the chrstians kept electing him.
Lebanon was originally every bit as anti-Israel as the other Arab states and took part in the Arab invasion in 1948. They've changed their tune somewhat because Israel rescued them from the PLO, but most Arab-American and Lebanese-American chrstians are fanatically anti-Israel.
American-style "Bible-believing" chrstians are a new phenomenon in the chrstian world and are unknown to the ancient churches. They are the chrstians who support Israel and their reward has been to be denounced as "not chrstian at all" by the Council of Middle East Churches.
Sixty or seventy years ago, Muslims in the Middle East were generally very inward-looking, pre-modern, non-Western. Arab Christians, on the other hand, had been exposed to Western ideas, like nationalism. Some of them turned towards Communism. Others became leaders of Arab nationalist movements.
But that's not really the case any more. The Muslim world has become politicized and militant or extremist movements abound. Among the remaining Christian Arabs, you don't find the same strong political passions. You'd be really hard-pressed to find Arab Christians as fanatical as Hamas or Hezbullah.
If you still Christian Arab Communists in Palestine in recent years (it's harder and harder to find Christian Arabs at all there now), it's because the alternatives were militant and extreme Muslim parties, but I'm pretty sure that the bulk of the leadership and membership of the successor party today are largely Muslim.
Lebanon was originally every bit as anti-Israel as the other Arab states and took part in the Arab invasion in 1948. They've changed their tune somewhat because Israel rescued them from the PLO, but most Arab-American and Lebanese-American Christians are fanatically anti-Israel.
Is it really surprising that there was animosity to Israel among Christian Arabs in the early years? Since then, Lebanese Christians are hardly going to be as fanatically pro-Israel as some people, but they're also hardly as "fanatically anti-Israel" as their Muslim countrymen.
You're playing a shell game here, making out that those who don't share your views are all equally fanatical, when that may not be the case. The relationship between Lebanese Christians and Israel may be based on common enemies, but such relationships aren't uncommon in politics.
The poster's original comment that it's not Arab Christians that Israel has to fear most is a valid one. There may not be much love lost, but their isn't the kind of zealotry that there is among the Muslims.
