I am only posting the link to the music video, for obvious reasons.
The mockery displayed in the video is typical of Shrinkers. For example, when the LCMS pastor posted "Because Christmas is not my birthday," he clearly mocked Holy Communion.

The only thing is that by watching this video you are going to lose over 6 minutes of you life that you will never get back. You are much better off reading a couple of Psalms in that time that is otherwise wasted.
However, the ironic thing is that many would find no problem with doing "Oh Come All Ye Faithfull" in that heavy rock style. After all isn't it "becoming all things to all people?" The sobering fact should be clear that Twisted Sister is mocking what is a beautiful Christmas song...and they know it. They (TS) must laugh heartily when many Christians today would actually think they are doing God's will by copying their antics.
Remember the Rock anthem, then Christian rock anthem, then Rock anthem once again, (this time by KISS), called "God Gave Rock and Roll to You?"
God gave rock and roll to you, gave rock and roll to you, put it in the soul of everyone.
Same refrain for every band that has done the song.
