I am bothered by the confusion of the issues. There’s a halachic issue and a political issue.
It would seem to me, that if this discussion would be about davening at the kosel, all but some neturei karta-like people would say something like “bleep” the arabs.
Which moves us on the the halachic issue. I am unlearned in this area and have no direct opinion as to whether to risk relying on heteirim here other than to encourage all to ask their rabbi their halachic questions.
