To her credit (I’m not a fan) Ann Coulter said once holidays are different for Muslims and Christians. At Easter and Christmas the US has families visiting loved ones, festive meals, gift giving and celebrations and Church attendance.
For times while Muslims observe their holidays such as Ramadan the airports and public buildings have extra guards and possible shutdowns for threats, there are bomb threats and sometimes abductions and killings by terrorists.
My favorite in Muslim holiday fun is the Shia holiday (I forget the name!) where they cut each other as acts of worship & celebration.
