Rabbi Lawrence Kelemen has a shiur about Xmas and New Year. A lot of mention about the Xian deity, JC Penny (as Rabbi Mizrachi refers him to) in this lecture. Interesting sources of the symbols of the stupid holidays based on avodah zara, of course. The most important part of the lectuer is how Jews were tortured in these holidays in their earliest celebrations.
To listen to the shiur go here.
