You really think that getting pissed off because a church that you don't even attend isn't going to have a Christmas sermon is "fighting for the kingdom of God"?
From your posts, you already feel that protestants are heretics so why do you even care? Don't you think that your energy could be better spent reforming the Catholic priesthood?
I am a Protestant.
I have issues with a Protestant ignoring what Scripture and the orthodox position of the church has been since day one, that Sunday is the new day of worship.
