Do you think the Settlers, given their propensity to stone Palestinians, and their attitudes toward that region (God gave it to them, expel Arabs, preferential rights for Jews) - would be willing to accept Arabs in their conclaves?
1. Oh come on! Did you want to play THAT justification game? 'Cause the Jews got this one in SPADES. Stones? Religious replacement theology and waqf beliefs? Expulsions? Preferential rights for Muslims? I'll see all that and raise you martyrs and kites and suicide bombers.
2. Yes. Of course Jews will accept Arabs. There is a 100 years of proof of it by the undeniable actual acceptance of Arabs in Israel.
1 and 2. I think it's valid to look at if we are going to talk about toleration. Your argument here is really one of degree. We agree that there is a problem with Palestinians accepting Jews. We should also look at whether the settlers - a powerful subset of Israel's demographics - would accept Arabs. Have they? How many Arabs live in their communities? Look at their attitudes expressed in the PEW poll and, more disturbing - you have close to half of all Israeli Jews supporting expulsion of Arabs.
