Jesus wasn't born December 25th. The day was Hijacked by Church & it's henchmen from Pagans who celebrated this day. No Angel or Star belongs on a tree for that was a Pagan ritual also to bring plants & trees inside at the end of harvest in the hope of encouraging a bountiful crop next year.
Those are just two reasons why I think it hysterical to watch Christians put an Angel atop their tree for Christmas Day :)
