Why one festival is more sexy than other?

I was seeing a movie named "Jhankar Beats". The movie was pretty decent and "young". However I saw they showed one girl (hindu) going to Church every Sunday. Now I am not against going Church or Mosque but it appears Church is a more glamorous place to speak about and show in a movie than say a Temple for a young lady. At the same time when the movie makers have to show a "traditional" heroine they would show her going to the Temple.

Is their a glamorization of certain religious principles? I could see students in colleges going out to buy cakes during Xmas, though none of them would be a Christian. I am not saying that celebrating XMas by Hindu is wrong, the point is why only Xmas and not Eid, which falls few days before Xmas. Again I believe the answer is Xmas is a more glamorous festival than Eid.

So what are we celebrating the festival for? To really celebrate it or just to be the part of this bottom less pit of enjoyment. How come certain festivals or days (like Valentine etc) became more "sexy" than some other days. I think the inherent inclination towards "having fun" and getting out of the usual drag of life is one factor and the marketers have also done a commendable work making money out of these festivals.

Every now and then we would have some days to boost sales of mall stores be it cards, apparels, food items etc. As human beings always are fun seeking its very easy to delude them and induce them into something which they may not at all want. This is one critical job of marketing. It may be termed as unethical however there is nothing really unethical about this practice. Thats the job of a marketer, to induce people, create demand and then fulfill it.

One more angle to these festivities is that how come Christian festival became bigger than a Muslim festival in terms of celebration by common people. Even I bought a cake last time to be cut in my room with few of my friends. What makes one festival more sexy and appealing over the others to a majority Hindu public despite the fact that both festivals belong to minority community. If at all we can celebrate all festivals in right spirit (a utopian argument) we would have lots of brotherhood in the country than the fickle consumerism.
