TAMPA -- More than 100 pleading, threatening and indignant e-mails have streamed into Hillsborough County School Board offices, some calling board members "gutless," "morons," and "a bunch of wimps." At issue is the board's vote to drop religious holidays from its school calendar, a decision that has drawn fire from national media, local officials and citizens. Hillsborough School Board members voted Oct. 25 to drop Yom Kippur and Good Friday from the 2006-07 school calendar, designating no religious holidays off except Christmas. Students may be absent on their religious holidays without penalty or restriction on the number of days.
