Christians-Are you getting tired of Christianity being minimized for atheists and muslims among others?

I am getting so tired of how being a Christian is almost seen as being a bigot or something bad. I notice how at CHRISTmas time, the bosses at my job said everyone needs to say happy holidays or you might offend someone and be fired for it. Another thing I noticed is how people make fun of Christians-especially in the media- but the other religions and those who don't believe at all have the utmost of respect from everyone. Why is this? Why do we support Scientology people like Tom Cruise and John Travolta?
