While the two, Issam Zeitoun and Sirwan Kajjo, were in Jerusalem, like any tourists, they visited the Kotel and put kipot on their heads out of respect for the Jewish holy spot.
Palestinian media immediately noted how they put on the kipot, as a subtle way to discredit them in the context of how they want to "normalize" with Israel, which is the horrid crime that Arab students cursed them for as they were speaking about how to save the lives of hundreds of thousands of Syrians.
Official Iranian and Syrian media, however, highlighted their attempt to discredit the pair by saying that Zeitoun and Kajjo were "practicing Talmudic rituals at the Wailing Wall."
The biggest crime that Palestinian media could tar the activists with was wanting to "normalize" with Israel. The biggest crime that Iran and its Syrian proxies could tar them with is associating them with Judaism.
The apologists for Iran, often citing its large Jewish community, should answer why this wonderful, tolerant state is so critical of "Talmudic rituals" that their own people engage in many times a day.
