All the people who are making it such a big deal in Nepal are mostly anti-Hindus and anti-bahun/chhetry. They are also the one who are petitioning to make cow slaughter legal in Nepal.

But you also have to accept the fact that mass slaughter in the name of sacrifice is immoral as well. But yes, as you pointed out, if you take statistics into account, Gadhimai is not the only event where animals are killed in mass, be it in the name of god or otherwise. I don't know what is more bad; protesting against Gadhimai festival or going into a cafe to eat a plate of momo afterwards. Take about hypocrisy and hatred.
