I'm glad to see someone taking the stage on this other than christians for once.
On a side note:
Originally the
Dedication of the Altar the Jewish holiday of Channukah ironically has become almost as unrecognizable as the modern iteration of christmas.
Basically, the Jews of the first century weren't showing up at the Temple Mount to light a menorah and give presents.
The following paper by a Karaite Rabbi gives more in depth historical discussion than your link.....if anyone is interested......
Festival of Dedication or Pagan Fire Festival?
