An ultra-Orthodox school told President Reuven Rivlin that his presence was not welcome on its grounds due to his public embrace of the gay and lesbian community following the stabbings at a Jerusalem pride parade earlier this month.According to Army Radio, the president was forced to cancel his planned official visit after the school communicated its displeasure to his aides."This is very difficult to hear," said Jerusalem Deputy Mayor Tamir Nir. "It's very saddening.""I'd like to express my support for the president," Nir said. "I'd really like for him to continue to raise his voice and not to be deterred by things like this."
