The IRS doesn’t know for sure that supporters of Israel are terrorists, but they have an anti-terrorism section to figure it out (because Arabs insisted they do so, and so they did). The special unit receives tax-exempt requests from those supporters and apparently keeps America safe by denying any such tax-exempt status if terrorism activities seem possible. Don’t you feel safer now? No evidence that pro-Palestinian groups get the same special attention.
Asked whether Jewish or pro-Israel applications are treated differently from other applications, Gary Muthert told House Oversight Committee investigators that they are considered “specialty cases” and that “probably” all are sent to an IRS unit that examines groups for potential terrorist ties…
Asked by investigators whether “all pro-Israel applicants went to the terrorism unit,” Muthert responded, “Probably . . . foreign activity, pro-Israel — if it is any type of foreign activity, it will go to the antiterrorism area.” Source: National Review
According to the article, the special units came into being in 2009 when the Arab-American Anti-Discrimination Committee complained that funds were being raised for Israel, from within the U.S. and some of those funds might go to the legal building of settlements in the West Bank. Those funders apparently became terrorists in the opinion of the U.S. Terrorism Organ we know as the IRS.
